Hi,
I know that the formula for computing the raw moments of 2-parameter Weibull distribution is:
Mu'n=b^n*Gamma(1+n/c), where b and c are scale and shape parameters, respectively.
However, I couldn't find any exact formula for a 3-parameter Weibull distribution. Is there any simple formula for it???
Thank you in advance
@markr,
Thank you for your reply.
Unfortunately, this is not what I need. It may be that the Weibull mean life is the first raw moment (but I'm not sure). If this is true, I don't know what the second and third raw moments are.
