Credit scoring is a method of modelling potential risk of credit applications. Traditionally, logistic regression, linear regression and discriminant analysis are the most popular approaches for building credit scoring models. Despite their popularity, quite a few limitations are known to be associated with these methods, such as being instable with high-dimensional data (also known as combinat...

BACKGROUND In the Copenhagen mammography screening program from 1991 to 2001, mammographic density was classified either as fatty or mixed/dense. This dichotomous mammographic density classification system is unique internationally, and has not been validated before. PURPOSE To compare the Danish dichotomous mammographic density classification system from 1991 to 2001 with the density BI-RADS...

Background The geno2pheno algorithm (g2p) can give dichotomous tropism based on a selectable “false positive rate” (FPR), reflecting the proportion of individuals inappropriately called “non-R5” and falsely excluded from taking CCR5 antagonists. The effect of replicate genotype measures and different FPR values remains controversial. Here we characterize different FPR “cut-points” in predicting...

Iterative voting is a social choice mechanism whereby voters are allowed to continually make strategic changes to their stated preferences until no further change is desired. We study the iterative voting framework for several common voting rules and show that, for these rules, an equilibrium may never be reached. We also consider several variations of iterative voting and show that with these ...

Background & Aims: The role of P53 and proliferating cell nuclear antigen (PCNA) genes in inflamed and non-inflamed odontogenic cysts is related to cell proliferation but it is unclear. The aim of this study was immunohistochemical evaluation of P53 and PCNA expression in inflamed and non-inflamed dentigerous cysts Methods: In the present study, 23 dentigerous cysts (12 inflamed and 11 non-infl...

We present an extrinsic evaluation of a clustering-based approach to computer-assisted scoring of short constructed response items, as encountered in educational assessment. Due to their open-ended nature, constructed response items need to be graded by human readers, which makes the overall testing process costly and time-consuming. In this paper we investigate the prospects for streamlining t...
