چکیده مقاله:

We consider a stage life testing model and assume that the information at which levels the failures occurred is not available. In order to find estimates for the lifetime distribution parameters, we propose an EM-algorithm approach which interprets the lack of knowledge about the stages as missing information. Furthermore, we illustrate the implementation difficulties caused by an increasing number of stages. The study is supplemented by a data example as well as simulations.

EM Algorithm and Missing Information for Left-Inflated Mixture Models

Data with bound-inflated responses are common in many areas of application. Often the data are bounded below by a real number (e.g., zero) with a substantial portion of observations at the boundary value. One approach to analyze such data is the general class of left-inflated mixture models. As a competitive alternative to the quasi-Newton BFGS method, we implement in this article the EM algori...

An EPQ Model for Product Life Cycle (Maturity Stage) with Deteriorating Items and Shortages

  A product life cycle is the life span of a product in which the period begins with the initial product specification and ends with the withdrawal from the market of both the product and its support. A product life cycle can be divided into several stages characterized by the revenue generated by the product. This study investigates inventory control policies in a manufacturing system for a si...

Generalized Linear Model for Binary Data with Missing Values: An EM Algorithm Approach

Abstract: A procedure is derived for estimating the parameter in case of missing data. The missing data mechanism is considered as missing at random (MAR) and non-ignorable. Here we use EM algorithm for logit link approach in generalized linear model. The logit link approach shows that it can effectively estimate the value of a categorical variable when we have information on the other categori...

An Algorithm for Stage Semantics

In the current paper, we re-examine the concept of stage semantics, which is one of the oldest semantics for abstract argumentation. Using a formal treatment of its properties, we explain how the intuition behind stage semantics differs from the intuition behind the admissibility based semantics that most scholars in argumentation theory are familiar with. We then provide a labelling-based algo...

Restoration of Congenitally Missing Lateral Incisors with Single Stage Implants: An Interdisciplinary Approach

The primary goal of the dental surgeon is to restore function as well as esthetics, and these objectives influence both the surgical and restorative phases of treatment. This report presents a conservative management of congenitally missing bilateral maxillary lateral incisors that was treated with a multidisciplinary approach between an orthodontist and a prosthodontist to redistribute spaces ...
