estGen: estimate a reparameterization of the hypothesis c_st

Description

estimates parameters from hypothesis lambda != gamma, where lambda is indepdent of gamma

Usage

estGen(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 2*S*T free parameters under this hypothesis.
