Abstract: Measurement error effect on the power of control charts for zero truncated Poisson distribution and ratio of two Poisson distributions are recently studied by Chakraborty and Khurshid (2013a) and Chakraborty and Khurshid (2013b) respectively. In this paper, in addition to the expression for the power of control chart for ZTBD based on standardized normal variate is obtained, numerical calculations are presented to see the effect of errors on the power curve. To study the sensitivity of the monitoring procedure, average run length (ARL) is also considered.
Keywords: power, zero-truncated binomial distribution (ZTBD), measurement error, average run length (ARL)
