Example of Partial Least Squares| JMP 13.2 The van der Voet T2 statistic tests to determine whether a model with a different number of factors differs significantly from the model with the minimum PRESS value.
Because there is no test statistic for the Bonnet method, Minitab uses the rejection regions that are defined by the confidence limits to calculate a p-value.
The statistic obtained is supposed to follow a standard normal distribution, which allows the calculation of the p-value. The AUC can also be used to compare different tests between them.
The Kullback's test is used to test the assumption of equality for intra-class covariance matrices. The statistic calculated is approximately distributed according to a Chi² distribution.
If you comment that business is up OR down, they will recommend a larger, spruced-up ad as the answer. The statistics they quote are out of date, and don't reflect today's realities.
Mixed: This statistic counts the number of cases where an operator will be inconsistent in the rating of a given part across repetitions. The proportion of such cases computed as the ratio between Mixed and the total number of parts is displayed.
In the case where it is assumed that the two data samples are from populations with equal variances, the test statistic under the null hypothesis has Student's t distribution with n+ m- 2 degrees of freedom, and the sample standard deviations are replaced by the pooled standard deviation.
This also is a two-tailed test which can be used with two or more variances. The hypothesis are similar to the ones in the Levene's test. Bartlett's statistic follows a Chi² distribution with k-1 degree of freedom.
