Double sampling X̄ control chart for a first order autoregressive process
(2008-09-01)
In this paper we propose the Double Sampling X̄ control chart for monitoring processes in which the observations follow a first order autoregressive model. We consider sampling intervals that are sufficiently long to meet ...

A Single Statistic for Monitoring the Covariance Matrix of Bivariate Processes
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
In this article, we present a new control chart for monitoring the covariance matrix in a bivariate process. In this method, n observations of the two variables were considered as if they came from a single variable (as a ...
