Tableau to DAX code

pk1593 — Mon, 09 Jan 2023 12:06:23 GMT

Can anyone help in converting this code to DAX?

S =
ABS([x]-LOOKUP([x],-1))/
(
SQRT
(
ABS(((([y] + LOOKUP([y],-1))/(SUM([z])+LOOKUP(SUM([z]), - 1)])))
*
(1-(([y] + LOOKUP([y],-1))/(SUM([z])+ LOOKUP(SUM([z]),-1)))))/ (1-((1/(SUM([z])+LOOKUP(SUM([z]),-1))))))
*
(1/SUM([z]) + 1/LOOKUP(SUM[z]),-1))
)
)

Hi,

For converting Tableau to DAX try utilizing ChatGPT. It works fast and provides answers like this:

S = ABS([x] - LOOKUPVALUE([x], -1)) / (SQRT(ABS( (([y] + LOOKUPVALUE([y], -1)) / (SUM([z]) + LOOKUPVALUE(SUM([z]), -1))) * (1 - (([y] + LOOKUPVALUE([y], -1)) / (SUM([z]) + LOOKUPVALUE(SUM([z]), -1)))) ) / (1 - ((1 / (SUM([z]) + LOOKUPVALUE(SUM([z]), -1)))))) * (1 / SUM([z]) + 1 / LOOKUPVALUE(SUM([z]), -1)))

You can also replace / with DIVIDE to avoid issues with 0. For the [x], [y] and [z] use the corresponding column refrerences.

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!

No this is incorrect.
I tried chatGPT but lookupvalue syntax is wrong and not a substitute for Lookup in Tableau.

I see, sorry about that. I just read the LOOKUP documentation in Tableau. The dax equivalent for LOOKUP would be OFFSET

Hi, pk1593

Can you provide sample data for testing? Sensitive information can be removed in advance. What kind of expected results do you expect? You can also show it with pictures or Excel. I look forward to your response.

Here S (col. highlighted in yellow) is the desired result which ia the significance t-testing forumula.
The table has 3 data points from 2019 to 2021.
x is in percentage, whereas y and z are weigted and unweighted counts of respective years.
