Help : How does JMP calculate Std Error for Least Squares Means?
Hi all, I'm having tough times understanding how JMP generates std error in the least squares means table. I have a model with two effects ie. factor 1 (3 categories) and factor 2 (2 categories) >> y = intercept+ factor 1 + factor 2. According to JMP, I'm able to get the LS mean of factor 1 by calculating the mean of predicted values. However, I couldn't get the Std Error that JMP rep...
