WebTo fit the Weibull distribution to data and find parameter estimates, use wblfit, fitdist, or mle. Unlike wblfit and mle, which return parameter estimates, fitdist returns the fitted probability distribution object WeibullDistribution. The object properties a and b store the parameter estimates. WebFor the Weibull distribution Thus We can use Solver to find the values of α and β that maximize LL(α,β). Alternatively, we can use Newton’s method based on the extension to the iterative approach described in Fitting Weibull Parameters via MLE and Newton’s Method when there was no censored data.
