CHISQ.INV.RT

Does JMP have an equivalent to excel's CHISQ.INV.RT function? I need it for FIT rate (reliability) calculations. Thanks in advance!

Re: CHISQ.INV.RT

Use "ChiSquare Quantile" function. See following screenshot to see how the results match.

Notice, the Excel function use right-tail probability, and you need 1 minus that probability for the JSL function.

BTW, I am curious, under what situation, do you need to manually calculate this quantity?
