Hi everybody,
How can I compute Omega Statistic in Stata? I don't find omega2 at
least.
It is for comparing the contributions of subsets of predictors in a
multiple regression model
(including generalized linear models, survival models
---------------
-omega2.ado- (please note the lowercase o in omega) still exists but
has been superceded by -effectsize- which is a bit more general. Both
of these commands only work with -anova-
I should note that omega^2 is designed to work woth fixed-effects
categorical variables. If you are looking at continuous predictors
then eta^2 or partial eta^2 is probably better. If you are using
-regress- than you might want to look for -regeffectsize-. None of
the above commands will work with survival models. I don't not know
any way to get omega^2 or eta^2 for survival analysis.
