I am having input like&nbsp; probability values and degrees of freedom. Can any help me in finding out this functionality. I have tried using F density function but not sure weather my results are correct or not.</P><P>&nbsp;</P><P>Dilip</P> Thu, 30 May 2019 10:07:38 GMT dilipkumar 2019-05-30T10:07:38Z https://community.jmp.com/t5/Discussions/F-distribution-Inverse-functinality/m-p/211167#M42281 <P>Hi,</P><P>i am trying to find out the F inverse value.

See <STRONG>Help</STRONG> &gt; <STRONG>Scripting Index</STRONG>. Then click the button at the top left corner to select <STRONG>Functions</STRONG>. Now select <STRONG>Probability</STRONG> in the first list and <STRONG>F Distribution</STRONG> in the second list. The arguments are the given quantile (F ratio), df for the numerator, and df for the denominator. It returns the probability of this F ratio or less.</P> <P>&nbsp;</P> <P>I think you are asking for the <STRONG>F Quantile</STRONG> function. (Select it in the second list.) The arguments are the given probability, df for the numerator, and df for the denominator. It returns the quantile (F ratio) corresponding to the given probability.</P> Thu, 30 May 2019 10:26:12 GMT https://community.jmp.com/t5/Discussions/F-distribution-Inverse-functinality/m-p/211177#M42282 Mark_Bailey 2019-05-30T10:26:12Z
