multivariate process capability indices (mpci) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. process capability is an important and commonly used metric for assessing and improving the quality of a production process. when quality charac-teristics of a product are correlated then an attractive comes close to mpc...

This research includes the Bayesian estimation of parameters multivariate partial linear regression model when random error follows matrix-variate generalized modified Bessel distribution and found statistical test represented by finding Bayes factor criterion, predictive under assumption that shape are known. The prior about is non-informative information, as well simulate on generated data fr...
