Feb 5, 2017 - Chi Square, Fisher F, and Student T Tables Previous Next

Greetings from PLANETQUANTUM.COM . We've uploaded Statistics Tables containing critical values of the Chi Square Distribution, Fisher F Distribution, and Student's t Distribution . For a little taste, see below. To see the complete tables, click Statistics Tables.

Readers might like to know how we created these tables. From our perspective, cumulative functions ChiSquareCum, FisherFCum, and StudentTCum are disguised incomplete Gamma and incomplete Beta functions and we know how to compute these functions. We apply Brent's method to the cumulative functions to get quantile functions ChiSquareQuant, FisherFQuant, and StudentTQuant which we use to generate the critical values appearing in our Statistics Tables.
