I'm working on a project I need to use SAS-callable SUDAAN to look at marginal predicted prevalence ratios (relative risk estimates) using weighted survey data. Plan to use backward elimination to build initial models.
SUDAAN does not support stepwise/forward/backward regression, at least not for survey procedures. So we're planning to do it "manually" (which I really didn't know was a thing--I was taught using the SELECTION = option with SAS), so I wanted to practice using normal SAS survey regression procedures.
So my question: when looking at -pvalues, which table am I looking at? I assumed I would be looking at the "Type 3 Analysis of Effects" table, selecting one-by-one the variable to remove that has the highest p-value, but I'm not 100% sure.
