qtweibull: Quantile Function for Truncated Weibull

In colinorourke/tweibull: Truncated Weibull Distribution

Description

This is an attempt to provide a more numerically stable version of the truncated Weibull distribution, especially for more extreme truncation points. Underneith the hood it relies on uniroot, which may issue errors. For this reason qtweibull should be considered the least stable component of this package. It's also about 50 times slower than stats::qweibull in cases where they both apply.

Usage

qtweibull(p, shape, scale, a = 0, b = Inf, log.p = FALSE, ...)

Arguments

p	(Numeric) Vector of probabilities
shape	(Numeric) Vector of Weibull shape parameters (default: 0)
scale	(Numeric) Vector of Weibull scale parameters (default: Inf)
a	(Numeric) Vector of lower truncation points
b	(Numeric) Vector of upper truncation points
log.p	(Logical) Whether p represents p or log(p) (default: FALSE)
...	Currently does nothing

Value

(Numeric) vector of quantile function values

Examples

qtweibull(0.5, 1, 5, 1.5, 2.5)
