Lindley: The Lindley Distribution

Description

Density, cumulative distribution function, and random generation for the Lindley distribution.

Usage

dlind(x, theta, log = FALSE)
plind(q, theta, lower.tail = TRUE, log.p = FALSE)
rlind(n, theta)

Value

dlind gives the density,

plind gives the cumulative distribution function, and

rlind generates random deviates.

Arguments

x, q

vector of quantiles.

n

number of observations. Same as in runif.

log

Logical. If log = TRUE then the logarithm of the density is returned.

theta

positive parameter.

lower.tail, log.p

Same meaning as in pnorm or qnorm.

Examples

theta <- exp(-1); x <- seq(0.0, 17, length = 700)
dlind(0:10, theta)
if (FALSE) {
plot(x, dlind(x, theta), type = "l", las = 1, col = "blue",
     main = "dlind(x, theta = exp(-1))")
abline(h = 1, col = "grey", lty = "dashed") }
