Calculates the mean and variance of an F variate.
An F variate is the ratio of two chi-squared variates.
Number of degrees of freedom of the first chi-squared variate that forms the F variate.
This input must be greater than 0.
Default: 1
Number of degrees of freedom of the second chi-squared variate that forms the F variate.
This input must be greater than 0.
Default: 1
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Expected mean of the variate.
Expected variance of the variate.
Error information.

This node uses the following equations to calculate the mean and variance of an F variate.
where k_{1} is the degrees of freedom of the first chi-squared variate that forms the F variate and k_{2} is the degrees of freedom of the second chi-squared variate that forms the F variate.
