摘要:

Estimates of kill and activity in Canadian mail surveys of migratory game birds have been subject to considerable survey errors. This article reviews the design of the surveys and describes the studies undertaken to estimate and correct for these errors. Recent developments in sampling and estimation procedures for these surveys are presented and changes in operational procedures described which have been adopted to implement these developments.

摘要:

Several ordinal measures of association for cross-classification tables are compared with respect to their stability when various grids are placed on a bivariate normal distribution. Kendall's taubusually fares better than Kendall's tauc, Goodman and Kruskal's gamma, and three extensions of Spearman's rho for cross-classification tables, in terms of approximating an associated measure for ungrouped data. The loss of efficiency of taubdue to grouping in testing the hypothesis of no association is considered and observed to be strongly related to the proportion of tied pairs of observations.

摘要:

Three related methods for assigning interval scale values to a set of ordered categories are proposed, based on the assumption that certain patterns of linear regressions exist among a set of variables. Technique I requires that the second administration of a variable be a linear function of the first. Technique II requires that two variables each be linear functions of one another (“symmetric linearity”). Technique III requires at least three linear regressions among three variables. The category values that are consistent with the assumed patterns of linear regressions are unique up to a linear transformation.

摘要:

It is shown that after base year revisions, different versions of the FRB Index of Industrial Production are similar in the time and frequency domains for the series as a whole. However, when measuring economic contractions, different versions yield substantial differences in the turning points, lengths, and amplitudes of cycles, which may be explained by the index number problem. These results suggest that when analyzing a particular historical period, it is best to use contemporaneously published data, if available.

摘要:

Should statistical forecasts be constructed by aggregating data to each level for which forecasts are required or aggregating the forecasts from the lower levels? The relevant literature suggests no general answer. In this study using actual data, forecasts aggregated from lower-level modeling were found best.

摘要:

The Randomized Response Technique, which was originally developed for qualitative purposes, is being developed for quantitative purposes, and the current article presents a new discrete quantitative RRT model. This model uses a predetermined combination of balls in the randomizing device, instead of asking an innocuous question. It has been shown that the procedures of administering the model is simple and that its efficiency of estimate is higher than the other currently available models.

摘要:

When large populations of small objects of similar size are to be counted, they are often spread (randomly) over a regular surface which is divided into equal areas. The proposed scheme may be used to obtain an estimate of the total number of these objects with specified precision (approximately), but after only a partial count. Approximate expressions are obtained for the first two moments of the estimate, and for the expected sample size.
