Our analysis of /linear regression focuses on parameter estimates, z-scores, p-values and confidence levels. Rarely in regression do we see a discussion of the estimates and F statistics given in the ANOVA table above the coefficients and p-values.
And yet, they tell you a lot about your model and your data. Understanding the parts of the table and what they tell you is important for anyone running any regression or ANOVA model.
Can you explain these estimates? In this training we will discuss these often overlooked calculations.
Specifically we will cover:
· the three sources of the sum of squares: model, residuals and total
· how the sum of squares are calculated
· how the sum of squares change as we add predictors to the model
· how they impact the calculations of r-squared, standard errors and confidence intervals
· the differences between Type I, Type II and Type III sum of squares
· what the F-test is testing and how does it compare to the t-test
· how to use the sums of squares to calculate effect size statistics
Upon completion of the training you will no longer fear being asked questions with regards to these overlooked and incredibly useful estimations.
Note: This training is an exclusive benefit to members of the Statistically Speaking Membership Program and part of the Stat’s Amore Trainings Series. Each Stat’s Amore Training is approximately 90 minutes long.
