Calculates the mean and variance of a non-central chi-squared-distributed variate.
A non-central chi-squared variate with k degrees of freedom and noncentrality d is the sum of the squares of k independent, normal random variables with standard deviations of 1 and means of d i , where .
Number of degrees of freedom of the random variable.
This input must be greater than 0.
Default: 1
Noncentrality parameter.
This input must be greater than 0.
Default: 0
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 random variable.
Expected variance of the random variable.
Error information.
The node produces this output according to standard error behavior.

This node uses the following equations to calculate the mean and variance of a non-central chi-squared-distributed variate.
where k is the degrees of freedom of the random variable and d is the noncentrality parameter of the random variable.
