Bartlett s chi-square test

C Model Discrimination - Bartlett s Chi-Square Test The m rival models with their mean SSR or error variances, s2, are pooled to a set of variances that are tested upon homogeneity. The following random variable is therefore defined [70] ... 

BARTLETT S TEST for homogeneity of CV s is applied in order to test the feasibility of "pooling the coefficients of variation" for any set of 18 generated samples (i.e., 6 at each of the 0.5, 1, and 2X OSHA standard levels). The following equation for the Chi-square, with 2 degrees of freedom, was used ... 

In order to pass Bartlett s test at the 1% significance level, chi-square must be less than or equal to 9.21 (chi-square has 2 degrees of freedom).
