Utility functions for the PC prior for range in PRW2

Description

Functions to evaluate, sample, compute quantiles and percentiles of the PC prior for the range parameter in the PRW2 model.

Arguments

Details

The statement Prob(range > r0) = alpha is used to determine lambda unless lambda is given.

Value

inla.prw2.drange gives the density, inla.prw2.prange gives the distribution function, inla.prw2.qrange gives the quantile function, and inla.prw2.rrange generates random deviates.

Note

The 'r' and 'q' functions are quite slow as the quantile-function needs to be computed.

Examples

    param <- c(10, 0.5, 1, 0)
    p <- inla.prw2.prange(10, param)
    q <- inla.prw2.qrange(p, param)
    print(c(10, q))
