Panel data dynamics and measurement errors: GMM bias, IV validity and model fit - a Monte Carlo study

Biørn, Erik; Han, Xuehui - 2012

An autoregressive fixed effects panel data equation in error-ridden endogenous and exogenous variables, with finite memory of disturbances, latent regressors and measurement errors is considered. Finite sample properties of GMM estimators are explored by Monte Carlo (MC) simulations. Two kinds...

Independent component analysis via copula techniques

Chen, Ray-Bing; Guo, Meihui; Härdle, Wolfgang Karl; … - 2008

Independent component analysis (ICA) is a modern factor analysis tool developed in the last two decades. Given p-dimensional data, we search for that linear combination of data which creates (almost) independent components. Here copulae are used to model the p-dimensional data and then...

Taguchi Method for Improvement in the Quality of Production Processes

Dura, Codruţa - In: Annals of the University of Petrosani, Economics 5 (2005), pp. 107-116

According to the Japanese specialist Taguchi, in order to obtain quality, even the conceptual phase imposes efforts in designing production process parameters, efforts which consist of finding the best parameters so that the product should be hyposensitized against disturbances. In other words,...
