F Distribution

These functions give you access to the F distribution. For more information about Fathom's distribution functions, click here.

fDensity(x, numDF, denomDF, scale, min)

fCumulative(x, numDF, denomDF, scale, min)

fQuantile(x, numDF, denomDF, scale, min)

 numDF = degrees of freedom (numerator)
denomDF
= degrees of freedom (denominator)
scale
= the mean of the distribution
min
= the minimum value

The density, cumulative, and quantile functions for the F distribution.

The x (the independent variable) and the two degrees of freedom are required. The two degrees-of-freedom parameters must be positive.

The scale is a scaling factor. The min is a horizontal translation.

defaults: scale = 1, min = 0.

You may also draw random values from this distribution: 

randomF(numDF, denomDF, scale, min)

A random value drawn from that distribution.

Here are some plots to help you understand the meaning of the numDF and denomDF parameters.
