Formula Notation ... Factor/covariate pattern Describes a single set of factor/covariate values in a data set. Minitab calculates event probabilities, residuals, and other diagnostic measures for …

Formula The Bonett procedure is not associated with a test statistic. However, Minitab uses the rejection regions defined by the confidence limits to calculate a p-value. For a two-sided …

Formula Notation ... MAD Mean absolute deviation (MAD) measures the accuracy of fitted time series values. MAD expresses accuracy in the same units as the data, which helps …

Parameter estimates Formula ... Standard error of parameter estimates The standard error is the standard deviation of the estimate of the parameter. The standard error provides a measure of …

Eigenvalue Formula The eigenvalues are the diagonal elements of the diagonal matrix in the spectral decomposition of the covariance or correlation matrix (see the topic "Eigenvectors"). …
