log likelihood and derivatives for Geom distribution

llikGeom(x, prob, full = FALSE)

Arguments

x: variable distributed by a geom distribution
prob: probability of success in each trial. 0 < prob <= 1.
full: Add the data frame showing x, mean, sd as well as the fx and derivatives

Value

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