Quantile Function of the Normal Distribution

Description

This function computes the quantiles of the Normal distribution given parameters (mean and sd) of the distribution computed by parnor. The quantile function of the distribution has no explicit form (see cdfnor and qnorm). The parameters have the following interpretations: mean is the arithmetic mean and sd is the standard deviation. The R-function qnorm is used.

Usage

quanor(f, para)

Arguments

f Nonexceedance probability (0 <= F <= 1).
para The parameters from parnor or similar.

Value

Quantile value for nonexceedance probability F.
