psi_extend: Simple Extension of a 'dd' Model beyond the Search Radius

In dwp: Density-Weighted Proportion

Simple Extension of a dd Model beyond the Search Radius

Description

Extend a distance model beyond the search radius via multiplication by a fixed, assumed constant rather than the default normalization used for extensible models. psi_extend should not be used with psiHat objects that were calculated with extent = "full".

Usage

psi_extend(psi, fwin)

Arguments

psi	psiHat object
fwin	fraction of carcasses assumed to lie within the search radius. If psi includes psiHat for multiple carcass classes, fwin should be either a vector with one value for each carcass class so that length(psi) = length(fwin) or a scalar (which assumes all carcasses, regardless of carcass class, have the same probability of landing outside the search radius).

Value

psiHat object extended beyond the search radius
