WebFits a three parameter Weibull distribution (alpha,beta,gamma) to the data provided. failures ( array, list) – The failure data. Must have at least 3 elements. right_censored ( array, list, optional) – The right censored data. Optional input. Default = None. show_probability_plot ( bool, optional) – True or False. WebFirstly, we generate some data from two Weibull distributions, combine the data, and right censor it above our chosen threshold. Next, we will fit the Mixture and Weibull_2P distributions. Then we will visualise the histogram and PDF of the fitted mixture model and Weibull_2P distributions.
