摘要:

This validation study examined the joint effects of question threat and method of administration on response distortion using four interviewing techniques. The level of threat was varied by asking questions about library card ownership, voting, bankruptcy involvement, and having been charged with drunken driving. The results indicated that response distortion increased sharply as threat increased. None of the data methods was clearly superior to all other methods for all types of threatening questions. Randomized response gave the lowest distortion on questions about socially undesirable acts, but even with this procedure there was still a 35 percent understatement of drunken driving.

摘要:

Although outdoor recreational use fluctuates daily, this time-varying feature has received little attention by economists and statisticians. In this paper, wilderness recreational use relationships are estimated, based on daily observations over the length of a given season, by (i) traditional econometric techniques and via (ii) time series analysis procedures promoted by Box and Jenkins [3]. In applying both sets of estimated relationships for forecasting purposes, the econometric equations generally proved superior. However, when predictions from both sets of equations were combined, the resulting forecasts obtained proved more accurate than either of the separate forecasts.

摘要:

Data from the 1970 census on work status of respondents in April 1965 are compared with those from the April 1965 Current Population Survey (CPS) for specific age-sex cohorts to gain some insight into the reliability of the retrospective data collected in 1970. The results indicate that on a net difference basis, the retrospective inquiry yielded reasonable approximations for most cohorts. The problem of gross versus net differences is reviewed briefly with respect to its implications for analyzing retrospective data.

摘要:

Statistics based on a theory of random graphs have been proposed as an analytic aid to assess the randomness of a clustered structure. Probability tables for two such statistics are tabulated. Exact values ofPn,v, the cumulative probabilities of the minimum number of edges needed to connect a random graph, are tabulated forn= 10(1)30(5)80-(10)100. Exact and approximate values ofEn,v, the expected number of components in a random graph withnvertices andvedges, are tabulated forn= 10(1)30(5)100.

摘要:

A dependent variable is some unknown function of independent variables plus an error component. If the magnitude of the error could be estimated with minimal assumptions about the underlying functional dependence, then this could be used to judge goodness-of-fit and as a means of selecting a subset of the independent variables which best determine the dependent variable. We propose a procedure for this purpose which is based on a data-directed partitioning of the space into subregions and a fitting of the function in each subregion. The behavior of the procedure is heuristically discussed and illustrated by some simulation examples.

摘要:

The age-parity-nuptiality model so far considered by demographers does not allow single women to have children, and all births are attributed to married women. The present paper is an attempt to extend the age-parity-nuptiality model by removing this restriction on single women. Mathematical expressions for the computation of intrinsic rates from the integral equation and projection approaches are derived. The model is applied to the U.S. female population for the year 1970.

摘要:

This article describes a generalized program for the computation of sampling errors. It employs computerized linearization of nonlinear estimates by the use of the first-order Taylor approximation. It can be used for any estimate derived from any “large” probability sample. In most instances the only inputs required are the weighted sample data and the form of the estimate whose precision is to be measured. In these cases, both the estimate and its sampling error can be produced with the same amount of data preparation and programming effort as is required to produce the estimate only.

摘要:

A major concern in large-scale surveys is the problem of subpopulation estimation (domain estimation). This paper presents a study of four estimators for estimating domain totals. The domain considered in the study is an area type of domain, that is, a domain consisting of a combination of a certain number of area units belonging to different strata This paper uses some actual data and some fictitious data to compare variances and mean square errors of the four estimators.

摘要:

The relationship of population density to distance has been of continual interest in urban economics. However, the true functional relationship between these two variables has not been formally tested. In this paper the Box and Cox [1] transformation technique is used to test five alternative specifications on statistical grounds. It was found that the semi-log and double-log relationships are not always the correct functional form to use in describing the relationship between the population density and distance within an urban area.

摘要:

A comparison is made between linear programming and weighted least-squares approaches to absolute deviation curve fitting. The computational results show that linear programming substantially reduces solution times while requiring only a relatively small amount of additional storage.
