The null hypothesis in Bartlett test is that variables are correlated only with themselves.
836) which approves the sampling adequacy; while zero confidence level obtained using Bartlett test shows the adequacy of induced factor model as well.
The Bartlett test of sphericity was used to verify the null hypothesis, according to which the correlation matrix is an identity matrix.
The probability associated with the Bartlett test for this research is p < 0.
D = Kolmogorov-Smirnov test statistic; W = Shapiro-Wilk test statistic; [chi square] = Bartlett test statistic.
Then the KMO and Bartlett test of Sphericity is carried out to ensure whether the correlation matrix has significant correlation among at least some of the variables.
Table 5 provides a summary of the Bartlett test statistics for the homogeneity of the error variances for all the securities that are cross-listed in the various group markets.
Factorability of items was confirmed by using the Bartlett test of sphericity and the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy.
Differences between standard deviations of the Ct measurements of two methods were tested for statistical significance using the Bartlett test (7) and are presented as mean relative variance values.
Table 2 shows KMO index, the Bartlett test statistic, freedom degree, and significance respectively.
The results of the Cochrane and Bartlett tests showed variance homogeneity for the analytical and within-person variances.
