Many approaches for solving problems in business and industry are based on analytics statistical modeling. Analytical problem is driven by the modeling of relationships between dependent (Y) independent (X) variables, we discuss three frameworks such relationships: cause-and-effect modeling, popular applied statistics beyond, correlational predictive machine learning, deductive (first-principle...

Statistical models for calculating sample sizes for controlled clinical trials often fail to take into account the negative impact that dropouts have on the power of intent-to-treat analyses. Empirically defined dropout correction coefficients are proposed to adjust sample sizes for endpoint analysis of variance (ANOVA) and analysis of covariance (ANCOVA) that have been initially calculated ass...

In the fear-avoidance (FA) model social cognitive constructs could add to explaining the disabling process in whiplash associated disorder (WAD). The aim was to exemplify the possible input from Social Cognitive Theory on the FA model. Specifically the role of functional self-efficacy and perceived responses from a spouse/intimate partner was studied. A cross-sectional and correlational design ...

OBJECTIVES To evaluate the reliability and validity of the PANAS (Watson, Clark, & Tellegen, 1988b) and provide normative data. DESIGN Cross-sectional and correlational. METHOD The PANAS was administered to a non-clinical sample, broadly representative of the general adult UK population (N = 1,003). Competing models of the latent structure of the PANAS were evaluated using confirmatory fact...
