estCs: estimate hypothesis c_st = c_s

In spiders: Fits Predator Preferences Model

Description

estimates parameters from hypothesis lambda_s = c_s * gamma_s

Usage

estCs(Xdst, Ydst, J, I, EM, em_maxiter, BALANCED)

Arguments

Xdst	matrix of sums of number of eaten prey species s during occurrence t; rows indexed by time, and cols indexed by prey species, TxS
Ydst	matrix sum of number of caught prey species s during occurrence t; rows indexed by time, and cols indexed by prey species, TxS
J	vector of predators caught in each time period
I	vector of number of days all traps were left out in a given time period
EM	boolean; whether or not EM algorithm is used
em_maxiter	integer specifying max number of EM iterations
BALANCED	boolean; whether or not data are BALANCED

Details

There are S*T + S free parameters under this hypothesis.
