Calculate the log likelihood of the binomial function (and its derivatives)

llikBinom(x, size, prob, full = FALSE)

Arguments

x: Number of successes
size: Size of trial
prob: probability of success
full: Add the data frame showing x, mean, sd as well as the fx and derivatives

Value

data frame with fx for the pdf value of with dProb that has the derivatives with respect to the parameters at the observation time-point
