Hi,
I have two models the first one is
y=x1+x2+x3
the second one
is
y=x1+x2+x3+x4
I need to bootstrap the standard errors of the
coefficient that I get as the difference (_b(x3)-_b(x3)) that is the
difference in the coefficient of the same regressor in the two
different regressions, may you help me how to do that? I need a
bootstrap of the standard errors I'm not interested in the bootstrap
of
the coefficients.
Thanks a lot
