log likelihood and derivatives for Weibull distribution

llikWeibull(x, shape, scale, full = FALSE)

Arguments

x: variable distributed by a Weibull distribution
shape, scale: shape and scale parameters, the latter defaulting to 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
