The Rice Distribution

Description

Density and random generation for the Rice distribution.

Usage

drice(x, vee, sigma)
rrice(n, vee, sigma)

Arguments

x vector of quantiles.
n number of observations. Must be a positive integer of length 1.
vee, sigma See riceff.

Details

See riceff, the VGAM family function for estimating the two parameters, for the formula of the probability density function and other details.

Value

drice gives the density, rrice generates random deviates.

Examples

## Not run: 
x = seq(0.01, 7, len=201)
plot(x, drice(x, vee=0, sigma=1), type="n", las=1,, ylab="",
     main="Density of Rice distribution for various values of v")
sigma = 1; vee = c(0,0.5,1,2,4)
for(ii in 1:length(vee)) lines(x, drice(x, vee[ii], sigma), col=ii)
legend(x=5, y=0.6, legend=as.character(vee),
       col=1:length(vee), lty=1)
