Hello,

I am conducting analyses using proportion data as my outcome. I am
using GLM with a logit link and the binomial family to carry out the
analyses. I would like to determine the effect size of my independent
variables. Here are two options I have considered:

Generate Odds Ratios using the -eform- command at the end of the GLM
statement. Does this make sense to do when my outcome is not
dichotomous?

Generate Marginal effects using -mfx-, holding my continuous variables
at their mean and dichotomous variables at 0.

Which method is most appropriate with a dependent variable that is a proportion?

For either method, how do I interpret (either the OR or dydx) for my
continuous variables and for my dichotomous variables?

I appreciate any insight you can provide,

Michelle
