buildQuasiObsForApplication: Expand discrete time survival data into quasi observations on...

In WinVector/QSurvival: Quick survival models by data transformation

Description

This function assumes time starts at 1 and counts unit increments. Expands into a regular pattern of quasi observations up to step observationWindowWidth for scoring of data (without known outcomes).

Usage

buildQuasiObsForApplication(d, observationWindowWidth, idColumnName,
  indexColumnName, parallelCluster = NULL)

Arguments

d	data.frame to expand
observationWindowWidth	scalar, step number to expand to
idColumnName	character scalar, column to write original row ids in
indexColumnName	character scalar, column to write quasi event indices into
parallelCluster,	if not NULL parallel cluster to perform the work.

Examples

d <- data.frame(lifetime=c(2,1,2),censored=c(FALSE,FALSE,TRUE))
buildQuasiObsForApplication(d,5,'origRow','sampleAge')
