Cumulative Distribution Function of the Normal Distribution

Description

This function computes the cumulative probability or nonexceedance probability of the Normal distribution given parameters of the distribution computed by parnor. The cumulative distribution function is

F(x) = \Phi((x-\mu)/\sigma) \mbox{,}

where F(x) is the nonexceedance probability for quantile x, \mu is the arithmetic mean, and \sigma is the standard deviation, and \Phi is the cumulative distribution function of the Standard Normal distribution, and thus the R function pnorm is used.

Usage

cdfnor(x, para)

Arguments

x	A real value vector.
para	The parameters from parnor or vec2par.

Value

Nonexceedance probability (F) for x.
