Logistic detection function
logisticdetfct(distance, theta, w, std = FALSE)
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).
