摘要:

On numerous economic and social issues, opinions of the informed segment of a population may differ substantially from those of the uninformed, to judge by results obtained from an experimental “public opinion survey.” Moreover the mere fact that a person is not informed about an issue does not deter him, as a rule, from offering an opinion when asked. Highly significant with respect to the validity of public opinion polls may be the marked tendency for those not informed about an issue (at times more than half of those interviewed) to lean toward a neutral position and for the misinformed to differ substantially in their opinions from the minority who were informed.

摘要:

This paper describes a method of estimating the intercensal population of counties by multiple regression analysis of symptomatic data. A test of the proposed technique indicates it to be more accurate than any of four alternate methods.

摘要:

The proximity of the 1960 Census makes timely an evaluation of existing census data from the standpoint of research uses; suggestions included in this paper are meant to furnish a basis for discussing plans for the forthcoming censuses. Despite many recent improvements, census data present numerous problems of quality, comparability, detail, and area classification of data, particularly in studies involving area sub-divisions of standard metropolitan areas or temporal comparisons. Among the needed improvements are (1) better coordination of the area units of statistical reporting, (2) reconstruction of historical series of metropolitan population and economic data, and (3) fuller recognition of metropolitan population as a distinctive residential category.

摘要:

Two procedures for ranking variances of normal populations are considered. The first is essentially a gap-test and effects a separation of the variances into two groups whenever the ratio of successive mean squares, arranged in ascending order of magnitude, exceeds a critical tabulated value. The second method is a more elaborate multiple decision procedure based on the distribution of the maximumF-ratio.

摘要:

A sufficient condition for the validity of the commonly used one-sided tests is that the underlying densityp(x, ω), wherexis the observed variable and ω the unknown parameter, possess a “monotone likelihood ratio.” In estimation, only monotone functions of the observed variablexshould be used as possible estimating functions of ω.
