In this article, a four parameter lifetime model called the Topp–Leone modified Weibull distribution is proposed. The suggested can be considered as an alternative to Kumaraswamy Weibull, generalized extend odd Lomax, Weibull-Lomax, Marshall-Olkin alpha power extended and exponentiated exponential distributions, etc. includes Topp-Leone Linear failure rate, Rayleigh distributions special case. ...
