Computing the exact confidence interval for Poisson Mean

[Anonymous]

Hi Experts 

how would you compute the exact confidence intervals for a Poisson Mean. Here is an example o fhow the calculation works, but i am interested in example 2 from the below link and in particular on how to calculate the following in BI this line (qchisq(0.025, 2*x)/2, qchisq(0.975, 2*(x+1))/2 )

happy to supply a test file if required.

Hi @Anonymous ,

If it is convenient, could you share some data sample which could reproduce your scenario and your desired output so  that I could make a copy and test.

Best  Regards,

hi Cherry

Many thanks for looking at my question and yes, there is a bulit in function within Power BI CHISQ.INV and family that populates the correct answer.
