NEW COMPREHENSIVE BOOK ON MAXIMUM-ACCURACY METHODS: Maximizing Predictive Accuracy (2016)

MOTIVATION

Procedures to identify mathematical models that explicitly yield optimal (maximum accuracy) solutions for samples were widely studied in the past century, with literatures emerging in fields such as symbolic logic, discrete mathematics, operations research, mathe­matical programming, set theory, decision-making, systems engineering, algo­rithms, automated manufacturing, com­puter science, machine intelligence, finance, transpor­tation science, man­agement science, and numerical tax­onomy. Broad-spec­trum consensus among disparate experts indicates that predic­tive accu­racy is an objective function worthy of being optimized.

In the Optimal (or “optimizing”) Data Analysis (ODA) statistical paradigm, an optimization algorithm is first utilized to identify the model that explicitly maximizes predictive accuracy for the sample, and then the resulting optimal performance is evaluated in the context of an application-specific exact statistical architec­ture. Discovered in 1990, the first and most basic ODA model was a distribution-free machine learning algorithm used to make maximum accuracy classifications of observations into one of two categories (pass or fail) on the basis of their score on an ordered attribute (test score). When the first book on ODA was writ­ten in 2004 a cornucopia of in­disputable evidence had already amassed demonstrating that statistical models identified by ODA were more flexible, transpar­ent, intuitive, accurate, par­simonious, and generalizable than competing models instead identified using an unin­tegrated menagerie of legacy statistical meth­ods. Understanding of ODA methodology skyrocketed over the next decade, and 2014 produced the development of novometric theory – the conceptual analogue of quan­tum mechanics for the statistical analysis of classical data. Maximizing Predictive Accu­racy was written as a means of organizing and making sense of all that has so-far been learned about ODA, through November of 2015.

DESCRIPTION

The perfect bound (softcover) textbook measures 8.5” wide, 11.5” tall, and 0.94” thick, and is typeset in Calibri size 10 font. There are 12 chapters and 408 pages (29 color), including 93 illustrations, 207 tables, and 491 references.

The book unfolds in four sections: Introduction (with three chapters: Pragmatic Considerations; Fundamental Concepts; Methodological Matters); Bivariate Methods (Categorical Attributes, Ordered Attributes); Linear Multiattribute Methods (General Linear Models; Maximum-Likelihood Models; Explicitly Optimal Models; Statistical Confounding); and Non-Linear Multiattribute Methods (Hierarchically Optimal CTA; Enumerated Optimal CTA; Globally Optimal CTA).

For researchers exploring ODA for the first time, the most appreciated aspect will likely be the intellectually transparent, intuitive presentation involving minimal use of a few simple equations: the optimal, maximum-accuracy para­digm is clear in its derivation, application, computation, interpretation, and dissemination. For researchers that use ODA in their work, the most appreciated reward is unquestionably the unmatched flexibility, simplicity, and accuracy of the statistical models – and their generaliza­bility across time and sample. ODA accommodates all metrics, requires no distributional assump­tions, allows for analytic weighting of individual observations, explicitly maximizes predictive accu­racy (overall, or normed against chance), and supports multiple methods of assessing validity. Finally, amply illustrated in Maximizing Predictive Accuracy, conducting maximum-accuracy statistical analysis is astonishingly straightforward, simple, and fast using commercially-available special-purpose software.

 SOFTWARE

UniODA®

Statistical models are useful to the extent that they provide accurate predictions and facilitate valid inferences. UniODA is the only software providing a univariate statistical model that explicitly achieves maximum predictive accuracy for any given sample, data configuration, and hypothesis.

  • Self-contained, stands alone, everything needed to conduct analyses quickly, with a minimum of effort.
  • Explained conceptually without equations, using clear, easy-to-understand examples.
  • The only software enabling manual classification tree analysis (CTA) to be conducted, and offering researchers pin-point control “inside” CTA models, for model exploration and fine-tuning.
  • Maximum-accuracy alternatives to t-test, logistic regression, chi-square, ANOVA, Mann-Whitney U, kappa, phi, discriminant analysis, autocorrelation, Markov analysis, log-linear model, probit analysis, and to a host of other traditional parametric and non-parametric statistical procedures.
  • Hold-out (cross-generalizability) and leave-one-out (jackknife) validity analysis; weighting by prior odds and/or by cost or return; exploratory or confirmatory hypothesis testing; and multiple sample analysis for diagnosing and circumventing Simpson’s paradox—all possible for every analysis.
  • Maximum-accuracy psychometric analyses, including parallel forms, split-half, inter-rater, test-retest, and intraclass reliability analyses; discriminant, convergent, and construct validity analyses; and multidimensional analysis of structure underlying bias in reliability and validity data.
