Testing for collinearity continues to be a controversial issue in the literature. Multicollinearity detection criteria, such as variance inflation factor, often fail detect true extent of multicollinearity. In this article, we propose utilizing Bayesian approach an attractive alternative. Under approach, recommend comparing marginal posterior regression parameters under two different priors. If...

We provide a collinearity based elementary axiomatics of optimal quantifier complexity ∀∃∀∃ for the geometry inside a triangle and reprove that collinearity cannot be defined in terms of segment congruence, the metric being Hilbert’s projective metric. MSC 2000: 51F20, 51A30, 51A45, 51G05

Price premiums are a key profit driver for long-term business relationships. For sellers in business-tobusiness (B2B) relationships, it is important to have appropriate strategies to negotiate price increases without trading off the relationships with their buyers. This paper aims to understand the annual price negotiation processes of companies by predicting whether a seller’s reservation pric...

Single-locus analysis is often used to analyze genome-wide association (GWA) data, but such analysis is subject to severe multiple comparisons adjustment. Multivariate logistic regression is proposed to fit a multi-locus model for case-control data. However, when the sample size is much smaller than the number of single-nucleotide polymorphisms (SNPs) or when correlation among SNPs is high, tra...
