Thanks Chris, but the method you mentioned is not what I want. Maybe I didn't make it clear.

However, those

I think something is not right. duh here is my sign..lol...but I am not sure even where this ast_register_file_version flag is in a config file or what step I have missed. I am doing a VOIP only

Dear All, I am trying to fit a simple linear mixed model (see below this paragraph) arising from a crossed factorial design with 2 factors and ubalanced number of replicates (from two to five) in each cell, but I keep getting an error message (see bottom of message). The model is: yijk = intercept + ai + bj + abij + ejik, where: "intercept" is fixed, and the crosss factors, ai, i =
