Hi,
I have noticed that EpsilonSkewNormal is removed from fitdist and Distribution Fitter since R2023a (was available in R2022a-b), I could not find the reason or announcement in the release note. I was wondering what is the reason behind this removal.
Thank you

To close this question
EpsilonSkewNormal has not been a part of fitdist or Distribution Fitter.
It is defined in one of examples in econometric toolbox (see below). I use this distribution frequently. When I moved my code to the R2023a, I forgot to run the following command
makedist -reset
To ensure that the probability distribution framework recognizes the new distribution.

Glad you figured it out.
It's surprising to me that my google search for EpsilonSkewNormal did not turn up that documentation page.

I just tried to run
pd = fitdist(randn(20,1),"EpsilonSkewNormal")
in R2022b, and got
Error using fitdist
Distribution name 'EpsilonSkewNormal' is unrecognized.
I also don't see that distribution listed in the R2022b documentation. (I don't have any older versions on my machine.)
So, if it is in some older version, you might need to look in older release notes.
Also, are you sure this was not a custom probability distribution object? I can find no trace of it on the internet.
