{{alias}}( t, k )
Evaluates the moment-generating function (MGF) for a chi-squared
distribution with degrees of freedom `k` at a value `t`.
If provided `NaN` as any argument, the function returns `NaN`.
If provided `k < 0`, the function returns `NaN`.
Parameters
----------
t: number
Input value.
k: number
Degrees of freedom.
Returns
-------
out: number
Evaluated MGF.
Examples
--------
> var y = {{alias}}( 0.4, 2 )
~5.0
> y = {{alias}}( -1.0, 5.0 )
~0.0642
> y = {{alias}}( 0.0, 10.0 )
1.0
{{alias}}.factory( k )
Returns a function for evaluating the moment-generating function (MGF) of a
chi-squared distribution with degrees of freedom `k`.
Parameters
----------
k: number
Degrees of freedom.
Returns
-------
mgf: Function
Moment-generating function (MGF).
Examples
--------
> var mymgf = {{alias}}.factory( 1.0 );
> var y = mymgf( 0.2 )
~1.291
> y = mymgf( 0.4 )
~2.236
