Subject: Differences test??
I run two models of the following form
I want to test whether the differences between the coefficient values is
statistically significant for example
Although i could easily do this in the second case using a t test (bw-bp),
I am not sure how to do this in the first case since the variable is
exactly the same (bx). The coefficient values though of bx differ because
there are different independent variables in each model.
any ideas of how to test for differences in this case?
