FischerGroupFi24Prime[] represents the sporadic simple Fischer group Fi_24'.
FisherHypergeometricDistribution[n, n_succ, n_tot, w] represents a Fisher noncentral hypergeometric distribution.
FisherRatioTest[data] tests whether the variance of data is one. FisherRatioTest[{data_1, data_2}] tests whether the variances of data_1 and data_2 are ...
FisherZDistribution[n, m] represents a Fisher z distribution with n numerator and m denominator degrees of freedom.
Fit
(Built-in Mathematica Symbol) Fit[data, funs, vars] finds a least-squares fit to a list of data as a linear combination of the functions funs of variables vars.
FittedModel[...] represents the symbolic fitted model obtained from functions like LinearModelFit.
FixedPointList[f, expr] generates a list giving the results of applying f repeatedly, starting with expr, until the results no longer change.
FixedPoint[f, expr] starts with expr, then applies f repeatedly until the result no longer changes.
Flat
(Built-in Mathematica Symbol) Flat is an attribute that can be assigned to a symbol f to indicate that all expressions involving nested functions f should be flattened out. This property is accounted for ...
FlattenAt[list, n] flattens out a sublist that appears as the n\[Null] th element of list. If n is negative, the position is counted from the end. FlattenAt[expr, {i, j, ...
