cdfgam_x

Calculates the upper limit of intergration of a cumulative gamma distribution function.

Prototype

	function cdfgam_x (
		p      : numeric,  
		shape  : numeric,  
		scale  : numeric   
	)

	return_val  :  numeric

Arguments

p

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

shape

A multi-dimensional array or scalar value equal to the scale parameter of the gamma density (shape > 0.0)

scale

A multi-dimensional array or scalar value equal to the shape parameter of the gamma density (scale > 0.0)

Return value

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

Description

Calculates the upper limit of intergration of a cumulative gamma distribution function.

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

Examples

Example 1 

     p     = 0.95
     shape = 3.0
     scale = 1.0

     x = cdfgam_x(p,shape,scale)
     print("x="+x)               ; x = 6.29579
