Division 162, for instance, experienced serious difficulties while approaching the village of Ghandouriyeh.2 Even though multiple axes of approach were available the IDF took the route along …

This paper is an intermediate result of a PhD research project undertaken by Lenny Visser with Cees Ruijgrok as supervisor. The final objective of this project is to measure thresholds in logistics outsourcing decisions, especially for the chemical sector. If we are able to measure the relative importance …

Several models in data analysis are estimated by minimizing the objective function defined as the residual sum of squares between the model and the data. A necessary and sufficient condition for the existence of a least squares estimator is that the objective function attains its infimum at a unique …

Anderson and Rubin and McDonald have proposed a correlation-preserving method of factor scores prediction which minimizes the trace of a residual covariance matrix for variables. Green has proposed a correlation-preserving method which minimizes the trace of a residual covariance matrix for factors. …
