Input data is log-transformed Check here if the data in the Input SAS Data Set is already log-transformed. Log-transformed data (continuous data) can be applied to fitting general mixed models . Note : No log-transformed count data can be applied for fitting generalized linear mixed models (GLIMMIX). GLIMMIX fits models to non-normal or normal data with correlations or nonconstant variability. To Indicate That the Input Data Is Log-Transformed: Check the box.
