using alternative models in glmulti
All,
I am working on a multiple-regression meta-analysis and have too many
alternative models to fit by hand. I am using the "metafor" package in
R, which generates AIC scores among other metrics. I'm using a simple
formula to define these models. For example,
rma(Effect_size,variance, mods=~Myco_type + N.type +total,
method="ML")->mod where Effect_size is the mean response for each
experiment, variance is the SE around the mean, mods are the variables,
and the method used to fit the AIC score is maximum likelihood
estimation. I thought I might be abl...

Effect size in multiple regression
Dear all,
is there a convenient way to determine the effect size for a regression
coefficient in a multiple regression model?
I have a model of the form lm(y ~ A*B*C*D) and would like to determine
Cohen's f2 (http://en.wikipedia.org/wiki/Effect_size) for each predictor
without having to do it manually.
Thanks,
Michael
