Help for function Chi2Test_p

_CD_ — Fri, 09 Feb 2018 16:15:14 GMT

Hi all !

I need some help to understand my problem for using the Chi2Test_p function.

I try the chart exemple given and it works fine. I don't really understand the way to calculate this but it's not really a pb.

Now I try to apply it on a specific set of data (see attachment). But Qlik Sense don't succeed to give me a result.

I simply use the function like that :

Chi2Test_p(Dim1,Dim2,Val)

Does anybody have an idea why I've no result ?

Thanks in advance for any help !

I think the data values make difference here. Even I don't understand this function much but I found few data cases work few not. For example, I created this sample data which shows some values.

I agree with you about the data values quality.

After "cleaning" data, the function accept to calculate something.

"Cleaning" data means :

- No null or 0 values

- Respect of my couple dimensions. For each value for Dim1, I need 2 Dim2.

This condition means :

Dim1	Dim2	Val
A	1	34
A	2	74
B	1	12
B	2	65
C	1	23
C	2	41
...	...	...

If I don't have the two lines for a Dim1 value, the calculation fails.

I don't really understand too and don't really know if the result is finally right
