tolongformat {simMSM}

Transforms Data Frame into Long Format Design

Description

Data frame with one line per event gets transformed to a data frame in a format that has as many rows as each subject has transitions for which he/she is at risk.

Usage

tolongformat(d, mpl)

Arguments

d

simulated data-set as the return object from the simeventhistories function.

mpl

model parameter list.

Details

In the format of the input data frame object d, the data are not yet suitable for a stratified Cox partial likelihood analysis: we need the data frame in a format that has many rows as each subject has transitions for which he/she is at risk. We will denote this as 'long format' in reference to the literature on multi-state model software, as for example on page 5 in de Wreede et al (2011).

Value

A list of data-sets.
