I received the following email from a reader after sending out the last article: **Opposite Results in Ordinal Logistic Regression—Solving a Statistical Mystery**.

And I agreed I’d answer it here in case anyone else was confused.

Karen’s explanations always make the bulb light up in my brain, but not this time.

With either output,

The odds of 1 vs > 1 is exp[-2.635] = 0.07 ie unlikely to be 1, much more likely (14.3x) to be >1

The odds of £2 vs > 2 exp[-0.812] =0.44 ie somewhat unlikely to be £2, more likely (2.3x) to be >2SAS – using the usual regression equation

If NAES increases by 1 these odds become [Read more…] about Opposite Results in Ordinal Logistic Regression, Part 2
