In gsl: Wrapper for the Gnu Scientific Library

Error functions

Description

Error functions as per the Gnu Scientific Library, reference manual section 7.15 and AMS-55, chapter 7. Thes functions are declared in header file gsl_sf_error.h

Usage

erf(x, mode=0, give=FALSE, strict=TRUE)
erfc(x, mode=0, give=FALSE, strict=TRUE)
log_erfc(x, mode=0, give=FALSE, strict=TRUE)
erf_Q(x, mode=0, give=FALSE, strict=TRUE)
hazard(x, mode=0, give=FALSE, strict=TRUE)

Arguments

x	input: real values
give	Boolean with TRUE meaning to return a list of three items: the value, an estimate of the error, and a status number
mode	input: mode. For GSL_PREC_DOUBLE , GSL_PREC_SINGLE, GSL_PREC_APPROX use 0,1,2 respectively
strict	Boolean, with TRUE meaning to return NaN if status is an error

Details

The zero functions return a status of GSL_EDOM and a value of NA for n≤q 0
