摘要:

This article is a generalization of the procedures developed by Steinhorst and Bowden (1971) for constructing confidence bands for the 100βth percentiles in the general linear model. Since the original procedure built these bands about a biased estimator of the 100βth precentile line, some other estimators were tried. While some improvement was noted, the results are not conclusive, suggesting that the best procedure has not been found yet.

摘要:

In an earlier article (Swamy and Mehta 1975), we formulated a particular decomposition for the coefficient vector in a relationship to be estimated from a time series of cross sections. Specifically, we expressed the coefficient vector as the sum of a common mean vector and two random vectors. One of these random vectors differs among individuals both at a point in time and through time, while the other differs among individuals only. In this article, we state some conditions under which the estimators of the first two moments of the coefficient vector developed in Swamy and Mehta (1975) are weakly consistent and asymptotically normal.

摘要:

It is proved that an uncertainty function is a geometric mean if and only if the rate of reduction of uncertainty is independent of the prior distribution.

摘要:

The recent method of Serfling and Wackerly (1976) for constructing fixed-width confidence intervals for the center of location is extended to includeMestimators. The resultant class of procedures is compared to the stopping times of Chow and Robbins (1965), as both the interval lengthdand intended noncoverage probability 2α converge to zero. Except in certain special cases, the stopping times are found to have different asymptotic distributions. The coverage probability of the Serfling-Wackerly class is found asdconverges to zero.

摘要:

A procedure is developed for obtaining upper and lower γ probability tolerance intervals for a proportion, β, of a population represented by a two-parameter Laplace or double exponential distribution. Both parameters are assumed to be unknown. The intervals are exact and are obtained by conditioning on the observed values of ancillary statistics for the parameters.

摘要:

The minimum absolute deviation (MAD) estimator may be used as an initial, or preliminary, estimator in a robust regression procedure. Alternative estimators have been developed by Hinich and Talwar (1975) and Andrews (1974). All three estimators are related to the median, and so their respective asymptotic properties can be compared relatively easily, at least in simple models. The conclusion which emerges from such comparisons is that the asymptotic properties of the MAD estimator are, in general, superior to those of the other two estimators. However, certain small-sample properties are also important in assessing the relative merits of the different estimators.

摘要:

In order to resolve the difficulties involved in inference from a sample of categorical data obtained by using a fallible classifying mechanism (usually inexpensive), we consider, as in Tenenbein (1970, 1971, 1972), the utilization of an additional sample. The second sample is subjected to a simultaneous cross-classification of its elements by the fallible mechanism and by some true (usually expensive) classifying mechanism. The setup is general; i.e., the discussion can be applied to any multidimensional cross-classified data obtained by unrestricted random sampling. Two methodologies are presented: (i) a combined maximum likelihood (ML) and least squares (LS) approach and (ii) a complete-LS approach. Both methodologies are illustrated using real data.
