SmokeOnset: Smoke Onset Data

In mdhglm: Multivariate Double Hierarchical Generalized Linear Models

Description

For 1,556 students in the Los Angels area, onset of smoking are observed at each of three timepoints a1; a2 and a3 where a1 is starting time for investigation, a2 is the 1 year follow-up and a3 is the 2 year follow-up (Hedeker, et al., 2015). These event times are grouped at the three intervals [0, a1), [a1, a2) and [a2, a3).
