ghy: Detection hazard function 'ghy' prob(detect | available at...

In david-borchers/LT2D: Line transect estimation in two dimensions

Description

This hazard function is a generalization of the form k(r,y)=a*r^(-b) from Hayes and Buckland (1983) p36, the generalization being that a parameter to be estimated is added to y. When this parameter is zero you get the form of Hayes and Buckland (1983) p36. Note: This function uses x for perp. dist., they use y.

Usage

ghy(y, x, b)

Arguments

y	Forward distance
x	perpendicular distance
b	parameter vector, where b[2] is log(theta); theta[1] is as per
