QUESTION
I run regressions over two groups with the same independent variables. Then, I would like to test whether the slopes from the two regressions are significantly different.
I have read that when the sample size and the variance are not equal between the two groups, it is recommended to perform a Welch's t-test. I found the t.test()
function however, I don't achieve applied it on slopes.
ANSWER
Answered 2019-Jul-08 at 23:34I am not quite going to answer your question exactly, but instead the more general question of how, in R, I would test the hypothesis of a difference in slopes across two groups with suspected unequal variance in the response variable.
OverviewThere are several options, two of which I'll go into. All of the good options involve combining the two datasets into a single modelling strategy, and confronting a "full" model which includes an interaction effect of gender and the slopes with a "no interaction" model which has an additive gender effect, but the same slopes of the other variables.
If we were prepared to assume the variance were the same in the two gender groups, we just use ordinary least squares to fit our two models to the combined data and use a classical F test:
