The robust estimator of the correlation coefficient and its use in a robust graphical test for bivariate normality with applications in aluminium industry are discussed. The estimator is a transformation of kendalls tau. Business and industrial improvement requires the use of information that can be extracted from multivariate data. The robust graphical test comes from an approximate MVN distribution and will help to identify outliers and confirms that the data comes from an approximate bivariate normal distribution.
