simdata {weightQuant}

Simulated dataset

Description

The data were simulated from a linear mixed model. Repeated data of the longitudinal outcome were simulated for 500 subjects. Death time was simulated depending on the (observed and unobserved) longitudinal outcome and on the binary covariate. Missing data before death were simulated using a logistic regression model including the binary covariate, the outcome at the previous visit and the observation status at the previous visit.
