grabsampling (version 1.0.0)

Probability of Detection for Grab Sample Selection

Description

Functions for obtaining the probability of detection, for grab samples selection by using two different methods such as systematic or random based on two-state Markov chain model. For detection probability calculation, we used results from Bhat, U. and Lal, R. (1988) .
