The correct tool for you depends entirely on which “PaCAL” or “Pascal” software you are looking to deploy. Because “Pascal” is used as the name for several completely different technologies, you should evaluate the options based on your exact industry and use case. 1. PaCAL: Python Probabilistic Calculator
If you are a data scientist, statistician, or engineer looking to do exact arithmetic on probability distributions, you are referring to the open-source Python package PaCAL. It allows you to treat random variables like ordinary variables to perform operations like addition or multiplication. The Alternatives
SciPy Stats: The industry standard for standard probability distributions, random sampling, and statistical tests.
SymPy Stats: A symbolic mathematics library capable of evaluating probability expressions symbolically rather than purely numerically.
