Is there an equivalent function to excel's BETA.INV() in JSL?

[#1]

I'm trying to calculate confidence intervals with the following formula that I use in Excel:

=BETA.INV(alpha/2, x, y -x +1)

I can't seem to find an equivalent function in the scripting index so am not sure if one exists. Any help is appreciated.

Hi @iamericha   The Beta Quantile function is what you are looking for.

In addition to @MRB3855 response, I will point you to the Scripting Index

     Help=>Scripting Index=<Beta Quantile

It will give you the definition along with an example
