Estimation of the cost function of a two-echelon inventory system with lost sales using regression
Multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. In this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. We have assumed the demand i...
متن کاملFactors Affecting Hospital Length of Stay Using Mixed Poisson Regression Models
Background and purpose: Modeling of Hospital Length of Stay (LOS) is of great importance in healthcare systems, but there is paucity of information on this issue in Iran. The aim of this study was to identify the optimal model among different mixed poisson distributions in modeling the LOS and effective factors. Materials and methods: In this cross-sectional study, we studied 1256 records, inc...
متن کاملRetrospective sampling in MCMC with an application to COM-Poisson regression
The normalisation constant in the distribution of a discrete random variable may not be available in closed form; in such cases the calculation of the likelihood can be computationally expensive. Approximations of the likelihood or approximate Bayesian computation (ABC) methods can be used; but the resulting MCMC algorithm may not sample from the target of interest. In certain situations one ca...
متن کاملForecasting daily supermarket sales using exponentially weighted quantile regression
Inventory control systems typically require the frequent updating of forecasts for many different products. In addition to point predictions, interval forecasts are needed to set appropriate levels of safety stock. The series considered in this paper are characterised by high volatility and skewness, which are both time-varying. These features motivate the consideration of forecasting methods t...
متن کاملPoisson Regression in Epidemiology
Various authors [3, 9, 11, 12] have noted that Poisson regression can be used to analyze cohort survival data (see Cohort Study). This formulation also leads to a unification of risk estimation based on internal comparison of rates among members of a cohort with various exposure levels and classical epidemiologic methods based on external rates that yield standardized mortality ratios or standa...
