PaCAL Changelog
What's new in PaCAL 1.5 Beta
Dec 4, 2012- beta version of arithmetic of dependent random variables (Bayesian network style)
- parts not related to dependent variables are as stable as in previous releases, so it is safe to use 1.5beta as default
New in PaCAL 1.1 (Dec 4, 2012)
- operations on two dependent random variables
- joint distribution models: normal, copulas
- joint distribution of two order statistics
- PaCal now depends on sympy
New in PaCAL 1.0 (Dec 4, 2012)
- order statistics
- noncentral distributions: Chi^2, F, Beta and T
- optimized routines for sum, average, max, min etc. of i.i.d. random variables
- Extreme Value Distributions: Gumbel, Weibull, Frechet
- better accuracy for Beta distribution
- methods interp_error and interp_error_by_segment return estimates of
- interpolation errors
- a warning is issued when dependent RVs are used in operations
- (use params.general.warn_on_dependent = False to suppress)
- bug fixes
