Department of Mathematics & Statistics, Kebbi State University of Science and Technology, Aliero Abstract: In this paper, Multivariate Techniques are applied to a Production/Manufacturing industry to examine various Chi-square Control Charts with Runs Rules. The Hotelling’s χ2 control chart is one of the most widely used multivariate charting procedures for monitoring the vector of means of several quality characteristics. It computes several multivariate control charts such as: Hotelling, Chi-squared, MEWMA, MCUSUM and Generalized Variance. Ten didactic datasets are included. It includes some tools for assessing multivariate normality: Mardia’s, Royston’s and Henze-Zirkler’s tests.

In the 1950's CUSUM (Cumulative Sum) control charts were introduced to obtained by taking square roots of the endpoints of two-sided confidence intervals 15 Dec 2008 It is helpful to review single-variable or univariate control charts before The LCL based on chi-square distribution can be ignored in practice
The Hotelling T^2 distance is a measure that accounts for the covariance structure of a multivariate normal distribution. It was proposed by Harold Hotelling in 1947
