Normal distribution

Dear DAX fellows,

I need to calculate some process statistics, and so far I found many statistical functions in DAX, including formulas for CHI²-distribution, exponential distribution and so on.

Why is there no normal distribution? In Excel this is NORM.S.DIST - but in DAX?

I don't want to prepare a lookup table giving the z-level and cumulated percentile... I'd rather like to do it in a measure.

Any ideas?

Many thanks in advance!
