I am interested in the algorithm used for cumulative probability distributions - specifically normal and chi square. Where might I find this?

Question

I simply want to know what algorithms are used to calculate cumulative normal and chi-square distributions.

Answer 1

Hi @John Morris

The algorithms for Excel statistical functions are not disclosed by the Microsoft development team.

In the instructions of some statistical functions, the optimization of the algorithm is only briefly mentioned.

Thanks for your understandings.
