We propose a lifetime distribution with flexible hazard rate called cubic rank transmuted modified Burr III (CRTMBIII) distribution. develop the proposed on basis of ranking transmutation map. The density function CRTMBIII is symmetrical, right-skewed, left-skewed, exponential, arc, J and bimodal shaped. model can accommodate almost all types shapes such as unimodal, bimodal, increasing, decrea...

This paper presents a model of urban traffic congestion that allows for hypercongestion. Hypercongestion has fundamental importance for the costs of congestion and the effect of policies such as road pricing, transit provision and traffic management, treated in the paper. In the simplest version of the model, the unregulated Nash equilibrium is also the social optimum among a wide range of pote...

Abstract A new compound Lomax model is proposed and analyzed. The novel distribution derived based on compounding the zero truncated Poisson exponentiated exponential distribution. density can be “monotonically left skewed,” right skewed” “symmetric” with various useful shapes. hazard rate “upside down bathtub-increasing,” “bathtub ( U -shape),” decreasing,” “increasing-constant” increasing.” R...

Coinage production of ancient powers such as Athens and Rome is usually inferred from die statistics monetary issues. The present work applies a Kaplan-Meier analysis resistance to failure 29 sets well-documented rate function assumes U-shaped form known in reliability engineering literature the ‘bathtub curve’. With geometric distribution being demonstrably violated for large fraction data set...

objective: repeated implantation failure (rif) is a condition in which the embryos implantation decreases in the endometrium. so, our aim was to evaluate the effect of local endometrial injury on embryo transfer results. materials and methods: in this simple randomized clinical trial (rct), a total of 120 patients were selected. the participants were less than 40 years old, and they are in thei...

We consider a novel sub-class of log-location-scale models for survival and reliability data formed by restricting the density of the underlying location-scale distribution to be log-concave. These models display a number of attractive properties. We particularly explore the shapes of the hazard functions of these, LLSLC, models. A relatively elegant, if partial, theory of hazard shape arises u...
