Logistic detection function

Logistic detection function

Usage

logisticdetfct(distance, theta, w, std = FALSE)

Arguments

distance

perpendicular distance vector

theta

scale parameters

w

scale covariate matrix

std

if TRUE uses scale=1

The routine returns a vector of probabilities that the observation were detected given they were at the specified distance and assuming that g(0)=1 (ie a standard line transect detection function).
