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)
log_erf_Z(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
