Understanding statistical power using noncentral probability distributions: Chi-squared, G-squared, and ANOVA [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2007
This paper presents a graphical way of interpreting effect sizes when more than two groups are involved in a statistical analysis. This method uses noncentral distributions to specify the alternative hypothesis, and the statistical power can thus be ...

Quantitative analysis of urban sprawl in Tripoli using Pearson's Chi-Square statistics and urban expansion intensity index

open access: yes, 2014
Urban expansion is a spatial phenomenon that reflects the increased level of importance of metropolises. The remotely sensed data and GIS have been widely used to study and analyze the process of urban expansions and their patterns. The capital of Libya (

A study on Freeman-Tukey test statistic under the symmetry model for square contingency tables

open access: yesCumhuriyet Science Journal, 2021
The symmetry model is the basic model in the analysis of square contingency tables. Multiple test statistics have been developed for the goodness of fit test. Freeman-Tukey test statistics is appropriate to be used in large samples.

A scaled difference chi-square test statistic for moment structure analysis

open access: yes, 1999
A family of scaling corrections aimed to improve the chi-square approximation of goodness-of-fit test statistics in small samples, large models, and nonnormal data was proposed in Satorra and Bentler (1994).

Adjusted Chi-Square Statistics: Application to Clustered Binary Data in Primary Care

open access: yesAnnals of Family Medicine, 2004
The frequency of randomized cluster trials is increasing in primary care research. These trials are differentiated by the randomization method, in which a group of individuals is randomly assigned to an intervention as a cluster rather than as ...
