Binomial Likelihood Function
MATLAB implementation:
nchoosek(n,y) * (p.^y) * ((1-p).^(n-y))
Log Binomial Likelihood Funcion
(exponential expressed as sum of logs)
(first term is constant; independent of model parameters)
MATLAB implementation:
sum( (y.*log(p)) + ((n-y) * log(1-p) ) )
GRTlnL.m and DEMlnL.m implementations:
-sum( (data.*log(predP)) + ((N-data).*log(1-predP)) )
