dGammaSD: Compute gamma stage duration densities.

In jknape/stageFreq: Estimate stage duration distributions and mortality rates from stage frequency data using MCMC

Description

The function is intended to be used in the calculation of numeric likelihoods.

Usage

dGammaSD(mu, cv, nGrid, tMax)

Arguments

mu	A vector of length equal to one minus the number of stages giving the mean stage durations for all but the last stage.
cv	A vector of the same length as mu giving the coefficient of variation, which is equal to one over the square root of the shape, for all but the last stage.
nGrid	The number of grid points to use.
tMax	The maximum time point in the grid (i.e. the right endpoint).

Value

A matrix of stage duration probabilities where the first column gives the grid and the remaining columns give the stage duration probabilities.

Examples

## Simulate gamma stage durations for ten individuals.
dGammaSD(mu = c(5,2,4), cv = c(1,.5,.3), nGrid = 20, tMax = 15)
