I have a series of three meta-regressions, where blocks of variables
were added, resulting in an initial R^2 of 27%, the second block adding
13% to R^2, and the third block adding 25% to R^2. This is a weighted
regression with random effects (i.e., metareg).
I want to report whether the change in R^2 is significant for blocks two
and three, but am uncertain how to obtain a test (F- or Chi-sq?) of R^2
change in Stata, especially since it for metareg with random effects.
Thanks,
Wendy
