Two-stage estimation using copula function

Authors

Abstract:

‎Maximum likelihood estimation of multivariate distributions needs solving a optimization problem with large dimentions (to the number of unknown parameters) but two‎- ‎stage estimation divides this problem to several simple optimizations‎. ‎It saves significant amount of computational time‎. ‎Two methods are investigated for estimation consistency check‎. ‎We revisit Sankaran and Nair's bivariate Pareto distribution as an example‎. ‎Two data sets (simulated data and real data) have been analyzed for illustrative purposes‎.

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...

BAYES ESTIMATION USING A LINEX LOSS FUNCTION

This paper considers estimation of normal mean ? when the variance is unknown, using the LINEX loss function. The unique Bayes estimate of ? is obtained when the precision parameter has an Inverse Gaussian prior density

A Two-stage Rank Test Using Density Estimation

For the one-sample problem, a two-stage rank test is derived which realizes a required power against a given local alternative, for all sufficiently smooth underlying distributions. This is achieved using asymptotic expansions resulting in a precision of order m-~, where m is the size of the first sample. The size of the second sample is derived through a number of estimators of e.g. integrated...

Estimation of Regression Model Using a Two Stage Nonparametric Approach

Based on the empirical or theoretical qualitative information about the relationship between response variable and covariates, we propose a new approach to model polynomial regression using a shape restricted regression after estimating the direction by sufficient dimension reduction. The purpose of this paper is to illustrate that in the absence of prior information other than the shape constr...

the two-stage estimation of energy consumption function in iran industry; based on logic model

knowledge of energyconsumption has many uses in industry. factors that are energy dependent have already been studied hence decision making on them are easier. energy demand studies of industry helps us to learn factors that are responsive to this demand. therefore planners can use these collected data in their decision making using the above factors. another use of energy demand can be used as...
