The Piece-wise exponential (Additive Mixed) Model
(PAMM; Bender and others (2018) <doi: 10.1177/1471082X17748083>) is a
powerful model class for the analysis of survival (or time-to-event) data,
based on Generalized Additive (Mixed) Models (GA(M)Ms).
It offers intuitive specification and robust estimation of complex survival
models with stratified baseline hazards, random effects, time-varying effects,
time-dependent covariates and cumulative effects (Bender and others (2019)),
as well as support for left-truncated data as well as competing risks,
recurrent events and multi-state settings.
pammtools provides tidy workflow for survival analysis with PAMMs,
including data simulation, transformation and other functions for data
preprocessing and model post-processing as well as visualization.

rpexp function

<dl><dt>n</dt>
<dd>number of observations. If <code>length(n) &gt; 1</code>, the length is
taken to be the number required.</dd>
<dt>rate</dt>
<dd>vector of rates.</dd>
<dt>t</dt>
<dd>vector of the same length as <code>rate</code>, giving the times at which
the rate changes. The values of <code>t</code> should be in increasing order.</dd></dl>
