In this paper, a new method is presented for quantifying dependence in output among wind farms connected to an electricity grid. Overall stability of a grid is an important consideration. If output of wind farms is highly correlated, serious stress can be placed on the local infrastructure and...

This paper aims at exploring consumers' purchasing behaviour towards paper products that could be derived from transgenic plantations. Field interviews were conducted to a randomly selected sample of 205 consumers, who declared that they would buy such paper products. Principal Components...

Parafac2 is the most flexible Simultaneous Component Analysis (SCA) model that produces an essentially unique solution. In this paper, we discuss how Parafac2’s special sign indeterminacy affects applications of SCA, and we reveal how an external criterion variable can be used to ensure that...

Fixed-effects models have become increasingly popular in social-science research. The possibility to control for unobserved heterogeneity makes these models a prime tool for causal analysis. Fixed-effects models have been derived and implemented for many statistical software packages for...

Correlated random-effects (Mundlak, 1978, Econometrica 46: 69–85; Wooldridge, 2010, Econometric Analysis of Cross Section and Panel Data [MIT Press]) and hybrid models (Allison, 2009, Fixed Effects Regression Models [Sage]) are attractive alternatives to standard random-effects and fixed-effects...
