Source: R/core.R
as241.Rd

Compute the standard-normal quantile for a probability using Wichura's (1988) Algorithm AS 241 (the PPND16 routine), the same algorithm underlying stats::qnorm().

Usage

as241(p)

Arguments

p

A probability in the open interval (0, 1).

Value

The standard-normal quantile (a numeric value) corresponding to p.

Examples

as241(0.975)   # about 1.959964
#> [1] 1.959964
