TandmobEmer {mixAK} | R Documentation |
This is a part of the Tandmob
data containing only
emergence times and some baseline covariates. Here, all left-censored
emergence times have been changed into interval-censored with the
lower limit of the intervals equal to 5 years of age (clinically
minimal time before which the permanent teeth hardly emerge). Also
censoring indicators are added to be able to use the data directly
with the NMixMCMC
function.
