Fuzzy classification maximum likelihood algorithms for mixed-Weibull distributions
In this paper we propose an efficient algorithm based on Yang's (Fuzzy Sets Syst 57:365-337, 1993) concept, namely the fuzzy classification maximum likelihood (FCML) algorithm, to estimate the mixed-Weibull parameters. Compared with EM and Jiang and Murthy (IEEE Trans Reliab 44:477-488, 1995) methods, the proposed FCML algorithm presents better accuracy. Thus, we recommend FCML as another acceptable method for estimating the mixed-Weibull parameters.
