Source: R/compute.Nht.R
compute.Nht.Rd

Compute individual components of Horvitz-Thompson abundance estimate in covered region for a particular subset of the data depending on value of group = TRUE (do group abundance); FALSE(do individual abundance)

Usage

compute.Nht(pdot, group = TRUE, size = NULL)

Arguments

pdot

vector of estimated detection probabilities

group

if TRUE (do group abundance); FALSE(do individual abundance)

size

vector of group size values for clustered populations

Value

vector of H-T components for abundance estimate

Note

Internal function called by covered.region.dht
