Statistical analyses

To account for the non-independence of individual observations within a year, and the large differences in sample size among groups, analyses were, where possible, performed on yearly means for the relevant sub-group. When appropriate, yearly means were squareroot or arc-sine transformed before analysis. All presented means and parameter estimates are back-transformed. All statistical analyses ...

A new statistical method for design and analyses of component tolerance

Tolerancing conducted by design engineers to meet customers’ needs is a prerequisite for producing high-quality products. Engineers use handbooks to conduct tolerancing. While use of statistical methods for tolerancing is not something new, engineers often use known distributions, including the normal distribution. Yet, if the statistical distribution of the given variable is unknown, a new sta...

Statistical power analyses using G*Power 3.1: tests for correlation and regression analyses.

G*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchner (2007) in the domain of correlation and regression analyses. In the new version, we have added procedures to analyze the power of tests based on (1) single-sample tetrachoric correlations, (2) comparisons of dependent...

Statistical analyses for round robin interaction data

This paper considers the analysis of round robin interaction data whereby individuals from a group of subjects interact with one another, producing a pair of outcomes, one for each individual. The authors provide an overview of the various analyses applied these types of data and extend the work in several directions. In particular, they provide a fully Bayesian analysis for such data, and use ...
