Beliefs are a key motivator of individual behavior. As such, an understanding of how individuals’ beliefs develop is a prerequisite to understanding decision-making and behavior. While rational choice theory posits a Bayesian framework for belief formation, status construction theories argue...

Research in psychology indicates that individuals often make inferences regarding unknown individual qualities based on potentially irrelevant (but socially observable) information. This paper explores occupational choices when individuals receive imprecise signals regarding ability and use the...

This paper explores a model of bounded rationality in evolutionary game play in which agent choice is based on a social psychological process of categorization and social inference. The computer simulation of the model demonstrates that agents' increasing ability to categorize opponents in the...

Cross-validation based point estimates of prediction accuracy are frequently reported in microarray class prediction problems. However these point estimates can be highly variable, particularly for small sample numbers, and it would be useful to provide confidence intervals of prediction...

Subspace state space algorithm of autors P. van Overschee and B. de Moor is considered and it's shown to be useful tool in parameter estimation of models in state space or classical forms. The results of N4SID algorithm is used as initial guess in iterative methods (such as prediction error...

Let[Sigma]be an unknown covariance matrix. Perturbation (in)equalities are derived for various scale-invariant functionals of[Sigma]such as correlations (including partial, multiple and canonical correlations) or angles between eigenspaces. These results show that a particular confidence set...

This paper is concerned with the use of regression methods to predict values of a response variable when that variable is naturally ordered. An application to the prediction of student examination performance is provided and it is argued that, although individual scores are unlikely to be well...

A well-known problem in multiple regression is that it is possible to reject the hypothesis that all slope parameters are equal to zero, yet when applying the usual Student's T-test to the individual parameters, no significant differences are found. An alternative strategy is to estimate...

Deteriorated water mains fail frequently causing service disruption and other inconvenience to the customers. Therefore, the utilities must conduct repair, rehabilitation and/or replacement in a timely manner to satisfy the needs of the customers. To succeed in this process the utilities must...
