Stymied by Regression Output?
Frustrated with how to read the coefficients for categorical variables? 
Panicked because you added a new variable or interaction, and all the other results in the model changed? 
Uneasy about understanding your regression or ANCOVA results well enough to write them up?

Most researchers can relate!  

Let’s face it: The statistics classes you’ve had so far have probably focused on straightforward models with only continuous predictors.

But real research, unfortunately, isn’t usually that simple.

At some point, you’re going to need to build a more complex model...

...one that includes multiple types of predictors with different types of scaling to test all sorts of research questions:

     • Binary and multicategory dummy variables
     • Centered, rescaled, and standardized variables
     • Predictors that are correlated with each other, though not quite collinear
     • Variables you had to transform to meet assumptions, but now look completely meaningless
     • Interactions between two continuous variables or between categorical and continuous variables
     • Quadratic terms that allow you to test a curvilinear relationship with a linear model
 

There are ways to set up the model so the interpretation is much easier.

When you understand linear regression coefficients for all types of predictor variables, you can build more sophisticated and accurate models.

...AND you can easily translate your findings into meaningful results.

Bridging the gap to a deeper understanding of regression coefficients is within your reach

Interpreting (Even Tricky) Regression Coefficients
A 6-Module, Online Workshop from The Analysis Factor

“Before the workshop, I didn’t realize how centering predictors can help decrease correlation or how to interpret an interaction between two continuous variables. As reviewers are demanding more complete and thorough analyses, these two skills will make my research more competitive.”
 
- Ursula S., Research Consultant

Module 1: Introduction and Review of Regression Models with Continuous Predictors

  • Review of the simple linear regression model
  • Review of the multiple linear regression model with continuous predictors
  • Interpreting regression coefficients when predictors are correlated
  • How interpretation differs for different types of predictors: covariates, confounders, suppressors, and more
 

Module 2: Scaling of Dependent and Independent Variables

  • Understanding unstandardized and standardized coefficients
  • How and when to center predictors to improve interpretability of coefficients
  • How transforming Y or X to meet assumptions affects the interpretation of coefficients
  • When centering affects the meanings of other coefficients in the model
 

Module 3: Multiplicative Terms for Continuous Predictor Variables

  • What quadratic terms tell you about the curved relationship between X and Y
  • How to break apart the linear trend from the curvature to understand both coefficients
  • Introduction to interactions
  • Interpreting interactions between two continuous variables
  • Interpreting interactions with quadratic terms–changing the curve
 

Module 4: Dummy Coding Binary Predictors: Main Effects and Interactions

  • The basic difference between dummy and effect coding
  • How to dummy code binary predictors, what the coefficients mean, and when including dummy variables changes other coefficients
  • How to interpret interactions for dummy-coded predictors
  • How including interactions changes coefficients of main effects (this is different from ANOVA!)
 

Module 5: Dummy Coding Multi-Category Predictors: Main Effects and Interactions

  • How to dummy code multicategory predictors and interpret their coefficients
  • How to interpret interactions for multicategory dummy predictors
  • How to interpret interactions between two dummy-coded variables
 

Module 6: Putting It All Together

Now that you understand all the pieces, we’ll start with how to intentionally choose the scaling and coding of variables, even when it seems a choice isn't available. Then we'll see how all the terms fit together in one big model, and how to break the model apart to understand each term. (This is often the trickiest part).​ ​​​​​​
 

Yes, I Want to Enroll!
I'm Karen Grace-Martin, workshop instructor

By the end of this workshop, my goal is for you to understand linear regression coefficients for all types of predictor variables. You’ll know how to set up your models so that later interpretation is much easier.

And when you do go on to learn multilevel models, logistic, Poisson, or any other kind of regression, you can focus on the unique challenges of that type of modeling rather than getting stuck on the fundamentals.

How Does It Work?

This course is a 6-module live, interactive online workshop from December 4, 2018 to January 2, 2019

All sessions are conducted online via live webinar. You can log in via phone or Internet. You’ll see the instructor’s screen to view the presentation…all from your own home or office.

During each webinar session, the instructor will cover core concepts and steps and will leave plenty of time to ask your own questions.

For each of the six modules, you will have a set of training resources and material.

In addition to the six training sessions, you’ll also meet with your instructor for four additional Q&A sessions where you can get additional assistance on workshop concepts, deepen your knowledge, and clarify any questions.

The training sessions are approximately 1.5 hours long, including time for questions.

The Q&A sessions are 60-minutes long. 

All 6 Workshop Sessions and 4 Q&A Sessions Are Recorded for Your Convenience.

Is This Workshop Right for You?
This workshop is for you if:

You’re learning an extension of linear regression (such as multilevel, logistic regression, or proportional hazard models) and aren’t sure how to understand the results.

You’re using linear regression or analysis of covariance — but you’re far from experienced at it and want to really understand the implications.

You’re prepping to defend your regression analyses and need a rock-solid understanding of the meaning of your models.

Your statistics training focused mostly on ANOVA, and not so much on linear regression. You’re finding your lack of understanding of regression is limiting your ability to apply appropriate analyses to your data.


It is NOT for you if:

You are looking for training on steps to RUN the model. This workshop is about understanding the results. It will help you make future decisions about how to scale variables and the usefulness of terms like interactions and polynomials, but it's really not about model building.

You already feel comfortable interpreting interactions, know how recoding predictors affects the information the model tells you, and are a whiz at dummy coding.

You have never run any data analysis before. If it's been a while, no problem--you'll love this workshop--but if you're a beginner, you won't.

FAQs

 
Q: What are the prerequisites for this workshop? 

This workshop is for researchers, not statisticians. That being said, you’ll get the most from this workshop if you have a MINIMUM of at least two statistics classes—an intro class, and a class that contains multiple regression or Analysis of Variance (ANOVA).


If you are a “beginner,” you may have trouble keeping up. However, if you’ve had one statistics class, but are working on regression and are confused, this workshop will be helpful.

Q: I haven't taken a statistics course in years. Will I be able to keep up?

As long as you have the suggested prerequisites, you should be fine. We know you don’t spend all day, every day, running regression analyses!

However, you WILL need to spend some time each week, both going over the training material and “getting your hands dirty” with some data. Expect to spend 2-3 hours per module reviewing the concepts and doing the exercises, and re-running class examples on your own.

And if you have questions during the workshop, make sure to attend the Q&A sessions and/or post on the Workshop Center to clarify anything you’re not clear on.

You know how this goes: The more time you put in, the deeper your understanding.

Q: What’s your refund policy?

Your registration fee is fully refundable up to 72 hours before your first class session.

Q: Do you offer student discounts?

Yes, we do! Current students with a valid ID can register for almost 40% off the standard rate. Click here to receive our student discount on all our workshops: https://www.theanalysisfactor.com/student-discount-list/

Q: Things are very busy at work right now, and I’m afraid I won’t have time to keep up. How much time per week does this really take?
​​​​​​​
We’ve worked hard to make sure people can take a workshop in the midst of their normal work life.

Each workshop training session is 1.5 hours, whether you attend live or listen to the recording.
​​​​​​​
Each week we have a one-hour Q&A session. You don’t have to attend, we just make those available so you can have any questions answered or listen in on others’ questions.
 

We provide exercises, answers and data sets, so you can practice what you’ve learned each week and get help in the Q&As. These will take you a few hours each module, up to 2 or so. The exercises aren’t required—you’re not graded. But we’ve gotten feedback that they’re very helpful, as it allows you to practice and figure out what you did and didn’t understand.

In other words, each week, there are approximately 3 hours of instruction, one hour of Q&A, and about 4 hours of practice time. So if you have a crazy hectic week during the workshop, you have catch up time. But If you have a crazy hectic month, you may be better off waiting as you won’t really have a chance to catch up.
 

One reminder: You have access to the workshop website, all materials, and a place to ask questions for a year. So if you get behind, you aren’t missing out. You can catch up on your schedule.

Q: I teach/work/sleep during this time and cannot attend live. Is there any way to register and access the webinar sessions later?
​​​​​​​
Yes! We have participants from many time zones with many different work schedules. In order to support our diverse student base, all modules – including the workshop sessions and Q&As — are recorded and made available to students within 48 hours. They’re screenshot video files, so you’ll hear the instructor talking and see her screen, just as live participants do. You can even submit questions for written answers any time between sessions. Many students take the entire workshop in this manner, never attending a session live.

 

Q: I’m outside the U.S. Can I still participate?
​​​​​​​
Yes. We have participants in our workshops from many different countries. You will want a fast internet connection and either a computer speaker or a telephone if you plan to attend live.

Q: Can I pay with Paypal?
 
Yes. When you check out, you can pay directly using our system or paying with Paypal. However, the three-payment option is not available using PayPal.
 
Q: Can I join the Q&A webinars from my tablet or phone?

Yes. You can join all webinar sessions from your Apple or Android device by downloading a free GoToMeeting app. A phone might be too small to see the details of tables, however, so we recommend a bigger screen.


​​​​​​​Q: This really isn’t a good time for me. Will you be offering this workshop again soon?

We don't have a set schedule for running each workshop. We try to schedule each workshop every 12-18 months, though very popular workshops may be offered more often. We are sometimes unable to re-run a workshop if the instructor becomes unavailable so there are no guarantees that any workshop will be run again.

If you think you'll need the material in the next half-year or so, I would suggest registering now. You’ll get all the materials to download and review at your convenience, and you can attend again for free any time in the next 12 months.
