pencal (version 2.3.0)

pbc2data: pbc2 dataset

Description

This list contains data from the Mayo Clinic primary biliary cirrhosis (PBC) study (1974-1984). It comprises two datasets, one with the survival and baseline covariates and the other with the longitudinal measurements. The datasets are a rearrangement of the `pbc2` dataframe from the `joineRML` package that makes them more suitable for analysis within `pencal`

Usage

data(pbc2data)

Format

The list contains two data frames:

• baselineInfo contains the subject indicator `id`, information about the survival outcome (`time` and `event`) and the covariates `baselineAge`, `sex` and `treatment`;

• longitudinalInfo contains the subject `id` and the repeated measurement data: `age` is the age of the individual at each visit, `fuptime` the follow-up time (time on study), and `serBilir`, `serChol`, `albumin`, `alkaline`, `SGOT`, `platelets` and `prothrombin` contain the value of each covariate at the corresponding visit
