Try the standard package Statistics`ContinuousDistributions` which
contains the WeibullDistribution. To create random numbers under any
distribution consult: Knuth d 1981 'The Art of Computer Programming'
Vols I & II, Addison-Wesley 2nd edition and Niedereiter H 1992 'Random
Number Generation and Quasi-Monte Carlo Methods', SIAM, Philadelphia,
PA. It should be possible to construct the fit using the Mathematica
functions 'Fit' and/or 'Interpolation' (see Wolfram 1996 The Mathematica
Book, section 3.8).
