摘要:

This address describes certain paradoxes and problems as they affect statistics singular, statistics plural and statistics political. It summarizes recent progress toward resolving the problems but stresses the need for major additional effort if statistics is, or are, to remain truly meaningful and viable.

摘要:

This article discusses possible problems associated with the Almon lag technique, caused by misspecification of the length of the lag or the degree of the polynomial. It is argued that the choice of the lag length is particularly treacherous. Finally, two studies of the relative importance of fiscal and monetary policy are reexamined, and it is shown how insufficient attention to these problems has significantly affected their conclusions.

摘要:

The accuracy of three estimators of sampling variance using non-replacement probability lattice samples was determined empirically on a microuniverse. A simple split-sample scheme, although biased, was superior to the unbiased Horvitz-Thompson and Yates-Grundy estimators.

摘要:

Inference procedures based on some simple rank statistics are proposed and studied for the statistical analysis of longitudinal data. These robust and asymptotically efficient procedures do not require the basic assumption of multivariate normality of the underlying distributions. The theory is illustrated with two examples.

摘要:

Migration rates by single years of age are used to estimate the number of years with moves an individual in the United States can anticipate in his lifetime. By age 18 a person can expect to have experienced just over one-fourth of his lifetime residential mobility; from age 18 through age 25 he can expect to experience almost 24 percent; and he can expect to experience one-half of his lifetime residential mobility shortly after his twenty-sixth birthday. These calculations were prepared according to type of move (within and between counties and states) and by race.

摘要:

This article attempts to define a birth table which describes the births generated from a particular cohort. There are two types of tables—abridged and complete. The interrelationship between different columns of a birth table is explained, and the application of such a table is also discussed. Finally a birth table for Belgium for the period 1928–32 is constructed using the data given by Keyfitz and Flieger inWorld Population.

摘要:

Data which appear to be binomial proportions sometimes exhibit heterogeneity which results in greater variation than would be expected under the binomial distribution. Methods for estimating means and associated inference procedures in a single sample and one-way classification have been developed by a least squares approach in which estimates of the heterogeneity variances are obtained by moments and used in weighting. Monte Carlo studies of the performance of this technique in moderate and small samples indicate that (1) these empirical weighting estimates have high efficiency relative to exact least squares estimates; (2) the variance estimators are nearly unbiased; (3) the resulting inference procedures are usually adequate for practical application.

摘要:

Stock market gains, their sources and economic effects have been the subjects of several recent studies, but the estimates of accrued gains generated in these studies often differ considerably, and do not meet some simple tests of consistency. In this article, an analytical framework is developed for computing capital gains consistently. The holdings of nonprofit institutions, which are generally not separated from the household sector because of lack of satisfactory data about them, are excluded to derive individuals' capital gains. Quarterly and annual estimates are presented for 1947–71, and the results are found to be fairly “robust” under a wide range of alternative assumptions about stock prices and the timing of net acquisitions.

摘要:

Using six simple models, the differing performances of the real Quantity and Income-Expenditure theories are noted for a sample of 13 developed countries. The degree of forced savings is suggested as a possible explanation for the differing relative performances of these two theories among countries.

摘要:

Computer simulation techniques were used to study the Type I and Type III error rates and the correct decision rates for ten pairwise multiple comparison procedures. Results indicated that Scheffé's test, Tukey's test, and the Student-Newman-Keuls test are less appropriate than either the least significant difference with the restriction that the analysis of variance F value be significant at α = .05, two Bayesian modifications of the least significant difference, or Duncan's multiple range test. Because of its ease of application, many researchers may prefer the restricted least significant difference.
