WebbTo simulate longitudinal data, we start with a ‘cross-sectional’ data set and convert it to a time-dependent data set. The original cross-sectional data set may or may not include time-dependent data in the columns. In the next example, we measure outcome Y once before and twice after intervention T in a randomized trial: WebbTherefore, we suggest using other packages such as simr which allows for linear and generalized mixed models. Custom code can also be written and for such specialized simulations we highly recommend the simstudy R package.
