摘要:

A comparison of the volume of industrial production in the United Kingdom in 1935 and 1948, using the full resources of the Census of Production, has recently been published. This provides an opportunity of testing the results obtained, much more rapidly but on more limited data, by an index of produetion. The index is shown to have underestimated the growth of production, which is in accordance with a priori expectations. The divergence between index and Census results for particular trades is frequently large; some instances are examined.

摘要:

* The author expresses with pleasure his indebtedness to Leo P. Crespi and to Fred W. Trembour for the privilege of introducing in September, 1952, the plan of duplicate samples into the public opinion surveys carried out by the American Embassy in Germany (then the U. S. High Commission in Bonn). In the original experimental work, and in earlier and later drafts of the manuscript and of the instructions for the procedure, I had the continual assistance of Josephine D. Cunningham, without whom this publication would have suffered indefinite delay.

摘要:

The Lot Plot Plan is a modified variables sampling inspection plan which calls for taking 50 observations and which makes use of the sample histogram. Depending upon the appearance of the histogram, various rules for acceptance are used. It is shown that despite use of a histogram no such plan can be distribution-free. The behavior of the plan is studied where the lot distribution is any of several “nearly normal” distributions including Student'st, the symmetric Beta distribution, thex2distribution and the mixed normal distribution. The probability of acceptance as a function of the fraction defective depends strongly on the distributional form of the lot. Little protection against non-normality is obtainable from study of the histogram for 50 observations.

摘要:

A simple method for testing the probability that a set of numbers is a sample from a known distribution consists of comparing the empirical cumulative distribution function of the sample,Sn(x), with the known cumulative distribution functionF(x). BothDn= maximum {Sn(x) –F{x)} andDn* = maximum |Sn(x) –F(x) | are random variables, independent of the special form ofF(x), ifF(x) is continuous. This paper contains more extensive tables of the percentage points in the distributions ofDnandDn* than have been published previously. These values are obtained by empirical modification of a known asymptotic formula.
