Summary
F cumulative distribution function (CDF).Unit
Probabilities
Declaration
Function FCDF(x: TSample; Nu1, Nu2: Integer): TSample;
Result
the F cumulative distribution function (CDF) for integer parameters Nu1 and Nu2 at the value X. Both Nu1 and Nu2 must be positive integer numbers, otherwise the result is NAN. The F cumulative distribution function is defined by the following equation:
where n1=Nu1 and n2=Nu2 are degrees of freedom, and G is the Gamma function.
The result of FCDF is the probability that a single observation from an F distribution with parameters Nu1 and Nu2 will fall in the interval [0,x].

Declaration
Procedure FCDF(X: TDenseMtxVec; Nu1, Nu2: Integer; Res: TDenseMtxVec);
Description
Calculates the F CDF for vector X using the parameters Nu1 and Nu2. The results are stored in vector Res. The Res Length and Complex properties are adjusted automatically. If vector X is complex, an exception is raised.| Copyright 2008 Dew Research |
