bipolar spectrum disorders may often go undiagnosed or unrecognized. the aim of this study was to determine the proportion of bipolar disorder symptoms in iranian patients with a major depressive episode.313 patients with a current dsm-iv-tr (diagnostic and statistical manual of mental disorders 4th ed. text rev.) diagnosed with a major depressive episode entered this cross-sectional study. thi...

Abstract Statistical clustering criteria with free scale parameters and unknown cluster sizes are inclined to create small, spurious clusters. To mitigate this tendency a statistical model for cardinality–constrained clustering of data with gross outliers is established, its maximum likelihood and maximum a posteriori clustering criteria are derived, and their consistency and robustness are ana...

Conjoint analysis has become the most used technique for measuring preferences for new products to be launched in the market. Experimental design models are key elements for its use in market research. Suchmodels involve amatrix in which attributes and levels are combined, making product concepts that respondents then evaluate. Experimental design has emerged as a key element in conjoint analys...

The method of statistical determination of smallest bans of probability measures on discrete spaces is offered. Consistency of the constructed estimates is shown. The application of the received estimates for testing of statistical hypotheses in the discrete spaces is constructed. It is shown that estimates of bans can generate consistent sequences of criteria in some sense.

In this article we define and investigate statistical analogue of convergence and Cauchy for double sequences in 2-normed space.We also obtain a criteria for a double sequence in 2-normed spaces to be a statistical Cauchy sequence. Mathematics Subject Classification: 40A05; 40A99, 46A70, 46A45

AIM to study the possible differences in the final diagnosis of chronic pancreatitis by using standard classification described by Wiersema et al. and the new classification proposed recently by Rosemont. MATERIAL AND METHODS forty-seven patients with the diagnosis of chronic pancreatitis were included in this study. The parenchymal and ductal criteria were studied, the patients were divided ...

In this part we describe the statistical test criteria which are used in Part I in the construction of computer-aided cytogenetic method of breast cancer diagnosis.

Synthetic peptides designed using criteria derived from statistical analyses of beta-barrel membrane proteins form channels in synthetic membranes at very low peptide:lipid ratios.
