This function will calculate the negative log likelihood value when the vector of binomial random variable and vector of corresponding frequencies are given with the input parameters.

NegLLMultiBin(x,freq,p,theta)

Arguments

x

vector of binomial random variables.

freq

vector of frequencies.

p

single value for probability of success.

theta

single value for theta parameter.

Value

The output of NegLLMultiBin will produce a single numeric value.

Details

$$freq \ge 0$$ $$x = 0,1,2,..$$ $$0 < p < 1$$ $$0 < theta $$
