Hello Kashif,

have a look at:


You will find:

WeibullDistribution[alpha, beta] and

CDF[WeibullDistribution[alpha, beta], x]  - cumulative distribution function
at x.

I do not know if the latter has a proper name.

Best regards,

Betreff: [mg44500] Question About Weibull Distribution

I have one quick question.  Summation of the Exponential Distribution is
Gamma Distribution. Is there any thing like Summation of Weibull
distribution?? and if there is then could you please give me its name and
CDF. Thanks
