weibull {IBMPopSim}

Weibull function.

Description

The Weibull (density) function is defined as

h(x) = \bigl(\frac{k}{\lambda}\bigr) {\bigl( \frac{x}{\lambda} \bigr)}^{k-1} e^{-(x/\lambda)^k}

with k, \lambda \in (0, +\infty).

Usage

weibull(k, lambda = 1)

Arguments

k

Shape parameter, a positive real number.

lambda

Scale parameter, a positive real number, defaults to 1.

Details

A C++ version of this function is available. See vignette('IBMPopSim_cpp') for more details.

Value

The Weibull density function dweibull with shape parameter k and scale parameter lambda, see dweibull.
