plaplace: Laplace (Double Exponential) Cumulative Distribution Function

Description

Laplace (double exponential) cumulative distribution function with mean equal to mean and standard deviation equal to sd.

Usage

plaplace(q, mean = 0, sd = 1, lower.tail = TRUE)

Arguments

q

Vector of quantiles.

mean

Population mean.

sd

Population standard deviation.

lower.tail

Logical; if TRUE (default), probabilities are \(P[X \le x]\); otherwise, \(P[X > x]\).

Value

plaplace gives the distribution function.

Details

The Laplace distribution has density \(e^{-|x-\mu| \sqrt{2} / \sigma} / (\sigma \sqrt{2}),\) where \(\mu\) is the mean of the distribution and \(\sigma\) is the standard deviation.
