log1mpexp: Numerically compute the value of log(1 - p + p * exp(-x))

In colinorourke/tweibull: Truncated Weibull Distribution

Description

Due to numerical accuracy issues with directly computing this function, a different approach is used that is hopefully more robust. The approach uses uniroot, and therefore may fail. This is an internal function to the package and no real error checking is performed on its inputs.

Usage

log1mpexp(log_p, a, b, shape, scale, ...)

Arguments

a	(Numeric) Lower truncation point
b	(Numeric) Upper truncation point
shape	(Numeric) Weibull shape parameter
scale	(Numeric) Weibull scale parameter
...	Arguments that get passed along to 'uniroot'
p	(Numeric) Numeric 0 <= p <= 1

Value

A numeric value
