In pammtools: Piece-Wise Exponential Additive Mixed Modeling Tools for Survival Analysis

Create matrix components for cumulative effects

Description

These functions are called internally by get_cumulative and should usually not be called directly.

Usage

make_time_mat(data, nz)

make_latency_mat(data, tz)

make_lag_lead_mat(data, tz, ll_fun = function(t, tz) t >= tz)

make_z_mat(data, z_var, nz, ...)

Arguments

data	A data set (or similar) from which meta information on cut-points, interval-specific time, covariates etc. can be obtained.
z_var	Which should be transformed into functional covariate format suitable to fit cumulative effects in mgcv::gam.
