Standard Normal Distribution, Inverse of a Standard Normal Distribution

Hello, good day to everyone. I would like to know if someone could help me with this problem.

 

I am trying to automate a predictive model, so for a calculation it is necessary to apply a standard Normal distribution and an inverse of a standard distribution, so I would like to know if there is any way to perform these calculations.

I know that by downloading the Use Predictive tools you can calculate the Standard Normal Distribution, however I cannot access the use of these tools. To make it clearer, the calculation that must be carried out, done in excel, is the following:

 

=NORM.DIST(X+NORM.INV.S.(Y))

X and Y are positive and negative numbers less than 1.

 

Thank you very much in advance to the people who can help me with this problem.

Hi @JhonC ! The alteryx abacus that @jdunkerley79  built has normdist and norminv which function similarly to excel: https://github.com/jdunkerley/AlteryxFormulaAddOns. I'd be glad to help if you have any problems installing it using it. You would use those functions in a normal formula tool.

It would be great to have this functionality as part of the 'off-the-shelf' formula tool!
