Dear Statalist readers,
I am trying to use the "hausman" command to compare the coefficients from a
fixed-effects model to those of a first-differenced model using the same
variables. The coefficient names from the FD model seem to be automatically
renamed to have a "D1" in them, making them different from those of the FE
model and causing the hausman command to return an error message. How can I
change the coefficient names from the FD model to match those of another
model? I can avoid this problem currently by using a different test for
strict exogeneity, but I'm sure this will come back to haunt me in the
future, such as when comparing FD to a random-effects model.
Thanks very much,
