I might be able to do a regression model but my statistical plan specifically references a linear mixed model. So I wanted to know if this estimate, p-value, and CI can be done by a linear mixed model through proc mixed instead of proc reg? ... View more

Hello, I am trying to explore the site effect in a clinical study where the site effect is significant. I have to find the weighted estimate using the proc mixed model "where the weight of each site is the inverse of the variance of each site estimate (which equals the inverse of the square of the standard error of each site estimate)." Am I able to use the standard errors produced by the ls means statement to produce the  “standard error of each site estimate”? ... View more
