摘要:

Following Duncan [3], the per hour cost of the process under the surveillance of a mean chart for controlling the mean of non-normal variables whose density function is represented by the first four terms of an Edgeworth series is obtained. The sample size and sampling interval which minimize the cost for detecting a particular shift in the process average are derived when the width of the control limits is specified. They are numerically determined for different non-normal situations by assuming various cost values when a particular shift in the process average is to be detected. They are presented in a table which compares the changes in optimum sample size and sampling interval due to changes in (a) the non-normal situation, (b) the shifts to be detected in the process average and (c) width of the control limits specified.

摘要:

Let x1x2··· xnbe any set of number satisfying Σ xi=0 Σ xi2=1. There are bounds on the range of xiwhen the set {xi} is ranked (a) by x1≥x2≥ ··· ≥ xnand (b) by |x1|≥|x2|≥ ··· ≥|xn|. These bounds are given. The applicability to finite populotionr is pointed out.

摘要:

In testing a normal mean with known variance, or a Koopman-Darmois parameter, an initial fixed number n of observations is followed by Wald's SPRT procedure. The conditional SPRT, given, and optimality properties in a certain class of tests are noted. For some parameter values, the PSPRT may have a lower ASN than a Wald SPRT with the same error probabilities.
