Abstract The present review provides a survey on basic models of ordered data and censoring mechanisms with focus lifetime data, failure reliability applications. Throughout, illustrations the generation process as well are used to visualize these procedures. By example we results assuming life testing model independent identically distributed measurements selected inferential for exponentially...

background: the brown-banded cockroach, supella longipalpa , is not as common as the german cockroach in iran. this species seeks out areas that are very warm most of the time, and prefer warmer area than what german cock­roaches pre­fer. there is relationship between development of instars and diet of cockroaches. the aim of this study was to determine the effect of different diets on biology,...

The present study attempts to establish a new framework to speculate customer lifetime value by a stochastic approach. In this research the customer lifetime value is considered as combination of customer’s present and future value. At first step of our desired model, it is essential to define customer groups based on their behavior similarities, and in second step a mechanism to count current ...
