# Statistical Functions Package: Normal Distribution

## Statistical Functions Package: Normal Distribution

Concept: Include basic Statistical Functions in Anaplan

Description: I miss some basic statistical functions among the available functions. These formulas are extremely useful when it comes to calculate chances or risks, which is a common and useful bit within the forecast calculations.

A good example is the lack of a counterpart in Anaplan for the Excel formula NORM.S.INV to retrieve the standard normal distribution of a probability %. But other helpful functions would be: NORM.DIST, NORM.INV, NORM.S.DIST

Why? Besides being formulas commonly used in some fields, at the minute, the workaround to carry out these calculations in Anaplan is quite space consuming in the WS: it is possible to calculate the Distribution of the Probabilities in Excel and copying the result (Probabilities and Distribution) into an Anaplan list. But depending on how accurate the Distribution is (how many decimal places), the list will contain more items and therefore will have a bigger size, reaching up to 2Gb for just the list alone.

Benefits: I ignore how hard would be to add the mentioned functions, but definitely they will save a lot of time to the model builders, quite some space in our WS and will not only broaden the applicability of Anaplan in other fields, but also making possible to model more advanced and complex solutions in Anaplan for those fields, expanding the Connected Planning concept.

I agree with @AlejandroGomez anaplan needs to integrate these basic functions as creating work arounds will eventually lead to performance issues as the model and users grow / dimensions.

Anaplan is a calculation engine it needs the functionality to be the best one which means having these basic statistical calculating functions.
