TreeAge Software and University of Sheffield collaborated on a poster presentation studying the relative bias between Markov models and Discrete Event Simulation models. The poster materials were presented at ISPOR Dublin in November, 2013.
In 2014 TreeAge Software Inc. undertook a comprehensive study of key statistical distribution implementations in TreeAge Pro software.
In collaboration with Department of Mathematics & Statistics of Williams College, Williamstown, MA the random number generator and following distributions: exponential, Weibull, normal, gamma, Rayleigh, Erlang, Bernoulli, binomial, Poisson and discrete uniform were subjected to various statistical tests.

TreeAge Software Inc. in collaboration with Department of Mathematics & Statistics of Williams College, Williamstown, MA created a reference document describing corresponding parametrization of selected distributions between TreeAge Pro, STATA, SAS and R.

TreeAge Pro models can be calibrated using Scientific Python (SciPy) libraries. An example of a calibration of a Markov 3 state progression model with Weibull transition hazards using Nelder-Mead optimization algorithm can be found by following this link. The compressed archive includes instructions for installing Python, as well as overview of the calibration process, TreeAge Pro model and working Python script. There is also a video showing the sample calibration session.
A research poster detailing results obtained by using different optimization algorithms was presented at ISPOR conference in Tokyo on September 11, 2018. The poster is available by following this link.
