The asymptotic non-null distribution is obtained for the modified form of the Pearson chi-square statistic studied by Dahiya and Gurland [3]. By utilizing this result the power is obtained for specific alternative distributions in testing for normality. This enables recommendations to be made as ...
FITEST: A Computer Program for "Exact Chi-square" Goodness-of-Fit Significance Tests This test is an alternative to the chi-square and Kolmogorov-Smirnov goodness-of-fit tests. Because it is based on less restrictive assumptions, the EC... C Romesburg,K Marshall,TP Mauk - Computers & Geos...
The Chi-Square test (χ2 test) is a family of tests based on a series of assumptions and is frequently used in the statistical analysis of experimental data. The aim of our paper was to present solutions to common problems when applying the Chi-square tests for testing goodness-of-fit, ...

Correlation Test - AssumptionsThe statistical significance test for a Pearson correlation requires 3 assumptions:independent observations; the population correlation, ρ = 0; normality: the 2 variables involved are bivariately normally distributed in the population. However, this is not needed for a ...
The foregoing example shows that, to test for variance using a sample from a normal distribution, we could use the chi-square table to obtain the critical value for the RR given α. Example 6.2.4 Suppose X is a single observation from a pdf f(x)=λxλ−1 for 0<x<1. With α=0....
Nonparametric correlations have fewer associated assumptions as compared to parametric correlations. Some of the most common that we will discuss include: phi; Cramer's phi; Spearman; and Kendall's tau. Many additional alternatives to the Pearson are then also presented. Phi coefficient The phi ...
