cdfchi_x

Calculates the upper limit of integration of a cumulative chi-square distribution function.

Prototype

	function cdfchi_x (
		p   : numeric,  
		df  : numeric   
	)

	return_val  :  numeric

Arguments

p

A multi-dimensional array or scalar value equal to the integral from 0 to return_val [0 < p < 1]

df

A multi-dimensional array or scalar value equal to the number of degrees of freedom of the chi-square distribution (0, +infinity).

Return value

A array of the same size as x. Double if any of the input arguments are double, float otherwise.

Description

Calculates the upper limit of integration of a cumulative chi-square distribution function.

The source code is from source routine "CDFCHI" from DCDFLIB (Double precision Cumulative Distribution Function LIBrary)
