Hallo,

Any chance of adding Maxwell–Boltzmann distribution?

#41 GEV CDF formula issue

Roby Joehanes — Wed, 21 Apr 2021 14:10:48 -0000

Hi there, sorry for the really late reply, but I checked the code here:
https://sourceforge.net/p/jdistlib/code/ci/master/tree/JDistLib/src/main/java/jdistlib/evd/GEV.java#l45

And I believe it is correct, just as you mentioned.
q = shape == 0 ? exp(-exp(-q)) : exp(-pow(max(1 + shape * q, 0), -1.0/shape));

I haven't changed that code since 2017. Did you get the code elsewhere or did I miss anything? Thanks!

GEV CDF formula issue

In file src/main/java/jdistlib/evd/GEV.java the formula

q = shape == 0 ? exp(-exp(-q)) : pow(exp(max(1 + shape * q, 0)), -1.0/shape);

is not correct, and should instead be

q = shape == 0 ? exp(-exp(-q)) : exp(-pow(max(1 + shape * q, 0), -1.0/shape));

The formula can be found in https://en.wikipedia.org/wiki/Generalized_extreme_value_distribution.

#40 Add Log-Logistic distribution

Thank you for the bug report. I added Log Logistic distribution into JDistlib. It should be slated for the next release. It is currently available in the code repository, which you can browse. Please feel free to use it and test it.

Would it be possible to add Log-Logistic distribution?
