Web1 Introduction to (Univariate) Distribution Fitting. I generate a sequence of 5000 numbers distributed following a Weibull distribution with: c=location=10 (shift from origin), b=scale = 2 and. a=shape = 1. sample<- rweibull(5000, shape=1, scale = 2) + 10. The Weibull distribution with shape parameter a and scale parameter b has density given by.
