cdfnor_x

Calculates the upper limit of integration of a cumulative normal distribution function.

Prototype

```	function cdfnor_x (
p     : numeric,
mean  : numeric,
sd    : numeric
)

return_val  :  numeric
```

Arguments

p

A multi-dimensional array or scalar value equal to the integral of the distribution from -infinity to return_val.(0,1)

mean

A multi-dimensional array or scalar value equal to the mean of the distribution (-infinity to +infinity).

sd

A multi-dimensional array or scalar value equal to the standard deviation of the distribution (0 to +infinity).

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 integration of a cumulative normal distribution function.

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

Examples

Example 1

```     p     = 0.95
mean  = 0.0
sd    = 1.0

x = cdfnor_x(p,mean,sd)
print("x="+x)                ; x = 1.64485
```
