We consider a uni ed description of classi cation rules for nearly singular covariance matrices. When the covariance matrices of the groups or the pooled covariance matrix become nearly singular, bayesian classi cation rules become seriously unstable. Several procedures have been proposed to tackle this problem, e.g. SIMCA, and Regularized Discriminant Analysis. N s and Indahl (1998) discovered...

The program-over-monoid model of computation originates with Barrington's proof that the captures complexity class $\mathsf{NC^1}$. Here we make progress in understanding subtleties model. First, identify a new tameness condition on monoids entails natural characterization regular languages recognizable by programs over from class. Second, prove known as $\mathbf{DA}$ satisfies and hence recogn...

In the present study, a positive training set of 30 known human imprinted gene coding regions are compared with a set of 72 randomly sampled human nonimprinted gene coding regions (negative training set) to identify genomic features common to human imprinted genes. The most important feature of the present work is its ability to use multivariate analysis to look at variation, at coding region D...

Credit scoring systems are currently in common use by numerous financial institutions worldwide. However, credit scoring with the microfinance industry is a relatively recent application, and no model which employs a non-parametric statistical technique has yet, to the best of our knowledge, been published. This lack is surprising since the implementation of credit scoring should contribute tow...

Anticipation increases the efficiency of a daily task by partial advance activation of neural substrates involved in it. Single trial recognition of this activation can be exploited for a novel anticipation based Brain Computer Interface (BCI). In the current work we compare different methods for the recognition of Electroencephalogram (EEG) correlates of this activation on single trials as a f...

Selectivity estimation is a parameter used by a query optimizer for early estimation of the size of data that satisfies query condition. Selectivity is calculated using an estimator of distribution of attribute values of attribute involved in a processed query condition. Histograms built on attributes values from a database may be such representation of the distribution. The paper introduces a ...

Online sales can be influenced significantly by customer reviews, and thus there are several studies on what makes an online review helpful to consumers. However, none of those researches address the helpfulness in context hedonic utilitarian types. This study examines how product type (hedonic utilitarian) moderates relationship between level (hedonicity utilitarianity) helpfulness. To test mo...
