rlaplace_truncated {genscore}

Generates laplace variables truncated to a finite union of intervals.

Description

Generates laplace variables truncated to a finite union of intervals.

Usage

rlaplace_truncated(n, lefts, rights, m = 0, s = 1)

Arguments

n

An integer, the number of samples to return.

lefts

A vector of numbers, must have the same length as rights. A non-empty vector of numbers (may contain -Inf), the left endpoints of a domain defined as a union of intervals. It is required that lefts[i] <= rights[i] <= lefts[j] for any i < j.

rights

A vector of numbers, must have the same length as lefts. A non-empty vector of numbers (may contain Inf), the right endpoints of a domain defined as a union of intervals. It is required that lefts[i] <= rights[i] <= lefts[j] for any i < j.

m

A number, the location parameter of the laplace distribution.

s

A number, the scale/dispersion parameter of the laplace distribution.

Details

Returns n random variables from the truncated laplace distribution with density proportional to \exp(-|x-m|/s) truncated to the domain defined by the union of [lefts[i], rights[i]].

Value

n random variables from the truncated laplace distribution.

Examples
