In hputter/mstate: Data Preparation, Estimation and Prediction in Multi-State Models

Recover baseline intensities (in the form of intensity_matrices) from a coxph() fit on multi-state data.

Description

Recover baseline intensities (in the form of intensity_matrices) from a coxph() fit on multi-state data.

Usage

baseline_intensities_from_coxmod(object, tmat, newdata)

Arguments

object	A coxph object describing the fit of the multi-state model, must contain a 'strata()' term.
tmat	A transition matrix as created by transMat.
newdata	A data.frame containing K rows per subject in the data, with K the number of transitions possible in the model. The following named columns must be present: id: Unique identifier of the subject this row relates to, must be numeric or character; trans: Transition number in the 'transMat' trans this row relates to; "variables": The subject-specific covariates (appearing in the coxph formula), ordered according to transition number in trans. Note that newdata must contain a column containing the variable which was used to determine the stratum of a transition in object (usually this is 'trans').
