I keep receiving an error message of 'model testing failure' for the 3dLMEr script. Here CRP_Group (between: 3) x Condition (within:2) x RRS (quantitative) are predictors, with covariates of Age and Sex. I tried several different versions of models but none of them worked. Could you help me to figure out what the problem is? Thank you.
