Advancing the use of effect size statistics

Developing algorithms and making effect size statistics accessible.
A parametric framework for multidimensional linear measurement error regression: In this paper, we discuss the fact that statistical measures of linear dependence, including covariance, correlation, and regression slope, are subject to the chain rule.
Nonoverlap proportion and the point-biserial association problem: Expository article published by ResearchOutreach.org.
Nonoverlap proportion and the representation of point-biserial variation: In this paper, we discuss the fact that statistics methodology is subject to the general physical principle that it is necessary to account for all of the degrees of freedom when studying a quantitative phenomenon. We develop a computational framework for generating the statistical parameters for point-biserial variation.
Factoring a 2 x 2 contingency table: In this paper, we show that a contingency table can be expressed as a product of marginal sum and proportion matrices. We also identify effect size measures for a 2 x 2 table that are invariant to variation in the marginal sums. The latter property is important for obtaining reproducible results in the analysis of categorical data.

Advancing the use of effect size statistics

The idea that statistical significance should be abandoned has received a lot of attention recently but it is not new, and efforts to replace p-value has been underway for some time. Perhaps the largest effort involves the development of effect size statistics. However, the large number of alternative effect size measures that have been proposed (Huberty, 2002) indicates that there are unresolved problems in this field as well. Only a small part of the large literature on these problems is cited here.
