WebbThere are three functions that facilitate this: viewBasis, viewSplines, and genSpline. The first two functions are more exploratory in nature, and just provide plots of the B-spline basis functions and the splines, respectively. The third function actually generates data and adds to an existing data.table. 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. For sequential analyses and adaptive designs the rpact package will also be very helpful. simstudy: Simulation of …

Webb8 feb. 2024 · The package simstudy has some functions that facilitate generating survival data using an underlying Weibull distribution. Originally, I added this to the package because I thought it would be interesting to try to do, and I figured it would be useful for me someday (and hopefully some others, as well). WebbThe function genCluster generates multilevel or clustered data based on a previously generated data set that is one “level” up from the clustered data. For example, if there is a data set that contains the school level (considered here to be level 2), classrooms (level 1) can be generated.
