Apply the scale CUSUM discussed in Section 9.1.8 to the data in Exercise 9.1
Answer to relevant QuestionsRework Exercise 9.1 using a standardized CUSUM. Exercise 9.1 Rework Exercise 9.23 using an EWMA with = 0.10. = 0.1; L = 2.7; CL = 0 = 734.5; = 108.7 Reconstruct the control chart in Exercise 9.29 using = 0.4 and L = 3. Compare this chart to the one constructed in 9.29 12.16 , CL = 0 = 950, UCL = 968.24, LCL = 931.76. Derive the variance of the exponentially weighted moving average zi. Set up an appropriate EWMA control chart for the valve failure data in Example 7.6. Use the transformed variable approach illustrated in that example.
