Mixed model for multiple measurements in a crossover study (SAS)

Webb30 nov. 1999 · A mixed effects model is developed for cross-over trials in which the response is measured repeatedly within each time period. Relative to previous work on repeated measures cross-overs, the methodology synthesizes two important features. First, our procedure eliminates preliminary testing for carry-over, defined loosely as the … WebbThe same model as specified above could be used in PROC MIXED and subject specified as a random effect. proc mixed ... specifies the code to be used for the analysis of replicate designs using PROC MIXED. proc mixed data=replicate; ...
