Consider the concentration data in Exercise 10.20. Construct a CUSUM chart on the residuals from the model you fit in part (c) of that exercise.
Answer to relevant QuestionsConsider the concentration data in Exercise 10.20. Construct a EWMA chart on the residuals from the model you fit in part (c) of that exercise. Set up a moving center line EWMA control chart for the temperature data in Exercise 10.24. Compare it to the residuals control chart in Exercise 10.24, part (c). To find the optimal , fit an ARIMA (0,1,1) (= EWMA = ...An x chart is used to maintain current control of a process. The cost parameters are a1 = $2, a2 = $0.50, a3 = $50, a′3 = $75, and a4 = $200. A single assignable cause of magnitude δ = 1 occurs, and the duration of the ...The data shown in Table 11.E1 come from a production process with two observable quality characteristics: x1 and x2. The data are sample means of each quality characteristic, based on samples of size n -= 25. Assume that ...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 ...
