simIDM 0.1.0
CRAN release: 20231211
New Features

estimateParams
estimates parameters of exponential and Weibull transition hazards using maximum likelihood for a given data set after usingprepareData
. 
corTrans
calculates the correlation between PFS and OS for a given set of transition hazards, andcorPFSOS
estimates this correlation for a given data set, optionally with a bootstrap based confidence interval.
Bug Fixes

ExpSurvOS
now returns 0 instead of NaN for large values of t. 
WeibSurvOS
now does not return an error for large values of t. 
PWCSurvOS
now does not return an error for large values of t. It also no longer returns values larger than 1. It is significantly faster, based on a closed form calculation instead of numerical integration. 
getSimulatedData
now also works when there are no transitions from progression to death, similarly forgetOneClinicalTrial
(which now warns if there are no such transitions at all).
simIDM 0.0.5
CRAN release: 20230127
 First CRAN version of the package.
 The package simulates illnessdeath models with constant, Weibull or piecewise constant transition hazards.
New Features
 Exponentially, Weibull and piecewise exponentially distributed survival times.
 Random censoring and eventdriven censoring after a prespecified number of PFS or OS events.
 Arbitrary number of treatment arms and flexible randomization ratio.
 Staggered study entry.
 Derivation of PFS and OS survival functions from transition hazards.
