HP.priors: Heligman-Pollard Parameter prior formation.

In strandCet: Estimation of Biological Parameters from Stranded Cetaceans

Description

Draws from a uniform distribution with bounds "pri.lo" and "pri.hi" to create the prior distribution of the Heligman-Pollard parameters necessary for the Bayesian Melding procedure.

Usage

HP.priors(pri.lo = c(0, 0, 0, 0.001, 0, 0, 15, 0, 0), pri.hi = c(0.15, 1, 1,
  0.5, 0.25, 15, 55, 0.1, 1.25), theta.dim = 9)

Arguments

pri.lo	Lower bound of the uniform from which the prior is drawn.
pri.hi	Upper bound of the uniform from which the prior is drawn.
theta.dim	The number of parameters to be estimated.

Value

A ((1000 * theta.dim) x theta.dim) matrix containing the 1000 * theta.dim sets of the Heligman-Pollard parameters drawn from a uniform distribution.

Examples

priors <- data.frame(priors.lo = c(0,0.5,0,0,0,0,6,0,1),
                     priors.hi = c(0.1,1,1,0.15,0.15,50,10,0.01,1.5))

HP.priors(pri.lo = priors$priors.lo,
          pri.hi = priors$priors.hi,
          theta.dim = 9)
