Maximum Likelihood Estimation of Dynamic Linear Panel Data Models with Fixed Effects

Kruiniger, Hugo - 2003

In this paper we consider inference procedures for two types of dynamic linear panel data models with fixed effects …. First, we show that the closure of the stationary ARMA panel model with fixed effects can be consistently estimated by the … conditional AR(1) panel model with fixed effects under various asymptotic plans. Then we show that when N tends to infinity but T …

An EOQ model for multiple products with varying degrees of substitutability

Eksler, Leonid; Aviram, Roei; Elalouf, Amir; Kamble, Aakash - 2019

In this paper, the authors present an EOQ model with substitutions between products and a dynamic inventory replenishment policy. Their key assumption is that many products in the market are substitutable at different levels, and that, in most cases, a customer who discovers that a desired...

Application of a Modified Generalized Regression Neural Networks Algorithm in Economics and Finance

Giovanis, Eleftherios - 2011

In this paper we propose an alternative and modified Generalized Regression Neural Networks Autoregressive model (GRNN-AR) in S&P 500 and FTSE 100 index returns, as also in Gross domestic product growth rate of Italy, USA and UK. We compare the forecasts with Generalized Autoregressive...
