Answer to relevant QuestionsConsider the first three process variables in Table 11.5. Calculate an estimate of the sample covariance matrix using both estimators S1 and S2 discussed in Section 11.3.2. Consider the cascade process data in Table 11.5. (a) Set up an individuals control chart on y2. (b) Fit a regression model to y2, and set up an individuals control chart on the residuals. Comment on the differences between ...Reconsider the situation in Exercise 11.2. Suppose that the sample mean vector and sample covariance matrix provided were the actual population parameters. What control limit would be appropriate for phase II of the control ...Consider the data in Table 12.1. Construct a bounded adjustment chart using = 0.3 and L = 10. Compare the performance of this chart to the one in Table 12.1 and Figure 12.12. Show how a 25 experiment could be set up in two blocks of 16 runs each. Specifically, which runs would be made in each block?
