摘要:

The construction of most comprehensive economic time series involves the estimation of some components for some dates by interpolation between values (“benchmarks”) for earlier and later dates. This is often done by using a related series known for all relevant dates.

摘要:

In problems where guidance to the proximity of a point is required, the probable success of the mission often is described by the probability of hitting within a given radius of the point. In this paper is presented a method of determining the probability of a hit within a given circle when it is assumed that the guidance error is distributed according to a bivariate normal distribution. This problem can be solved readily if the random error variables are independently distributed along two orthogonal axes with equal standard deviations and if they are not biased relative to the target location. Since these assumptions often are not valid, a series solution to the general problem is provided with an analysis of the error introduced by considering only a finite number of the terms.

摘要:

For testing the hypothesis that all the categories in a multinomial distribution are equally likely, a sequential test is proposed which at each stage of the sampling observes whether the observation falls in the set of categories containing the largest number of earlier observations. It rejects the hypothesis if at too many stages the observation does fall in that set of categories. The properties of the test are discussed.

摘要:

Nearly all of the distribution-free tolerance intervals that have been considered in the statistical literature are such that each endpoint consists of a sample order statistic or is unbounded. For two-sided intervals, many other possibilities are available. One purpose of this paper is to call attention to these additional possibilities, and to discuss their advantages and disadvantages. The principal purpose, however, is to show how to construct specialized two-sided tolerance intervals for use in investigating situations of two types. For the first situation, the probability concentration in the central part of the population is investigated. For the other, it is desired to investigate the probability concentration about a specified point. In both situations, the specialized intervals presented are not difficult to apply. For the first situation, permissible additional information can be used to obtain intervals tending to have shorter lengths than those not exploiting this extra information. In the other situation, the relative emphasis placed on the part of the interval to one side of the specified point, as compared to the part on the other side, can be specified.

摘要:

This paper proposes a multi-stage procedure for the selection of the best of several populations, allowing more observations to be made on the more successful treatments. To this end, a weighting function operates on the results accumulated up to any one stage to determine the proportion of observations to be taken from each population for that stage. The paper is restricted to consider only binomial populations. Simulation experiments utilizing five somewhat arbitrary weighting functions indicate that this method has a higher probability of selecting the best population than conventional equal sample size experiments.

摘要:

The output of domestic manufacturing plants exhibited increasing relative concentration between 1939 and 1958, but in 1958 the degree of relative concentration declined slightly from the 1954 level. The results do not reflect manufacturing company or ownership distributions. The trend in relative concentration of output seems to reflect changes in average value added by manufacture for the establishment size classes. During the 1939–1954 period the number of smallest size establishments increased much more rapidly than the largest size establishments. However, the average contribution to industrial production of the smallest establishments showed a much lower rate of increase than for the largest establishments. The 1954–1958 period was characterized by similar growth patterns for all establishment size classes.

摘要:

This paper deals with the population interpretations of measures of association for cross classifications. A new pair of (asymmetric) coefficients is introduced and interpreted. They are shown to be related both to Kendall'sτband to Goodman and Kruskal's τ, and their relation to Kendall'sτcis discussed. Second, Goodman and Kruskal's τ is interpreted as an analogue of the correlation ratio, suitable for unordered categorical data. This interpretation rests on a certain function, designated the “ordinal analogue of the variance,” of a univariate (ordered) frequency distribution, which enters into both Kendall'sτband Goodman and Kruskal'sτ.

摘要:

Practical application of price index theory demands the use of expedients and compromise which, when translated into detailed procedures for index calculation, makes the Bureau of Labor Statistics' Consumer Price Index a specific but limited measure of price change. Examination of the constants and variables in the index aggregate, and some possible changes in the classification of these factors, leads to a conclusion that the definition of measurement with respect to the true cost of living index concept cannot be altered merely through modification of index procedures.

摘要:

The concept of plant and equipment capacity is widely used in analyzing economic developments; but currently available measures of capacity show major discrepancies. The present paper reviews the uses, the definition, and the techniques of measuring capacity. A review of the principal uses suggests that capacity is intended to serve as an indicator of short-run cost conditions. This purpose in turn suggests certain criticisms of common definitions of capacity and leads to a new definition in terms of the percentage difference between marginal and average cost. The uses and the definition are the basis for a number of observations relating to techniques used to measure capacity.
