NettetPROC MIXED is widely used for statistical analyses of clinical data in pharmaceutical research. Although Proc Mixed is specially designed to fit fixed -effects models, it can also model random and mixed -effects data, repeated measures, spacial data, data with heterogeneous variances and auto -correlated observations. NettetIn particular, REML is used as a method for fitting linear mixed models. In contrast to the earlier maximum likelihood estimation, REML can produce unbiased estimates of variance and covariance parameters. The idea underlying REML estimation was put forward by M. S. Bartlett in 1937.
