@aloctavodia is this what you were broadly looking for?

The beta distribution is defined on the 0-1 interval. So for any beta distribution 100% of the mass will necessarily be inside that interval. In other words it is not posible to define a beta distribution with a mass less than 1 if the lower bound is 0 and the upper bound is 1.

Hi @nishant42491 Let me know if you need help.

Hi @nishant42491 Let me know if you need help.

hey there, I was a bit confused about how to compare the values of the fitted distribution. maybe use the distribution parameters which we receive from maxent let me know what you think.

Also, I have included a minor fix to the mode value error included in the beta_mode function. The function does not converge when mode = lower bound or mode = upper bound hence a strict inequality is needed for that case.

i have tried to fix this in my latest commit.

[nishant42491]

yea, you are right the dist parameters should be symmetric. I have added a fix for that.

[aloctavodia]

Almost there, you need to run black.

You can install https://pre-commit.com/ and it will alert you of errors with linters before committing.

[nishant42491]

yep, black seems to have fixed all the linting issues

I have also set the default plot keyword to True in Beta_Mode which should fix issue #325. I have linked the issue through the description of this PR.
