摘要:

A multitude of constantly changing problems must be faced and successfully resolved by an umbrella-type organization such as the American Statistical Association with its broad objectives, diverse activities and heterogeneous membership. However, the fact that the Association is broad based undoubtedly accounts for its strength (over 10,000 members) and endurance (established in 1839). The multiple-faceted aspect of the Association should be considered an important asset resulting in the opportunity for healthy interactions of differing kinds of people and ideas. The author contends that, even in the face of dislocations and accelerated change in many areas of modern life, the membership has the leadership qualities to make any needed adjustments and continue the development of the Association as a viable and vigorous organization, provided we cooperate with mutual respect and tolerance, despite our differences, and continually remold ourselves, subsequent to such adjustments, as a diversified but single scientific and educational community.

摘要:

This article derives a necessary condition for the independence of permanent and transitory components of a series when the permanent component is any weighted average of past, present and future values of the observed series and the transitory component is the difference between the contemporaneous observed and permanent values of the series. This restrictive necessary condition is derived assuming a most elementary stochastic specification of the observed series. A specific example of the restrictiveness of this condition is afforded if the permanent component of a series is generated by the Koyck or exponentially-weighted expectations model. For this leading example it is possible to derive the theoretical correlation between the permanent and transitory components of the series as a positive valued function of the coefficient of expectations adjustment. Finally, we discuss the importance of these results to Friedman's [3] permanent income theory and suggest a modification of that theory.

摘要:

The method of canonical correlation between sets of dummy variables is used to assign weights to the categories of occupational mobility tables, in order to test two assumptions: 1. The socioeconomic distance between occupations determines the correlation across individuals in a mobility table. 2. The relative status of occupations has remained constant over time. The weights which yield the maximum correlation are found to correlate very highly with measures of socioeconomic status, thus validating the first assumption. Since the maximum correlation between fathers' and sons' occupations is obtained by assigning similar weights to both sets, the second assumption is also validated.

摘要:

Construction cost indices have often been used to represent changes in house prices because no data on housing transactions, suitable for computing a broad-based index of house prices are available. In this article a technique for isolating price changes from estimates of market value is developed and used to derive a price index for nonfarm one-family houses of all types (excluding mobile homes) in the United States for the years 1947-64. Theoretical and empirical evidence is also presented to show that, in general, an index of construction cost would not reflect house prices accurately.

摘要:

In this article we first construct the input cost and input productivity price index for the Japanese construction industry and note the significant difference between the two. Next, we obtain, together with the two indexes, the output price index for government apartments and find that the input productivity index gives a much better approximation. Our output price index is the hedonistic price index. In the last section we compute capital stock for several industries and briefly discuss the bias in the growth rate of capital in using the input cost index.

摘要:

A method is presented for the design of experiments and the fitting of polynomial models where the experimentation involves not only mixture components but process variables as well. The experimentation is performed in a region of operation comprised of an ellipsoidal region in the mixture components and an ndimensional rectangular region in the process variables. The designs discussed are standard designs for factorial experiments.

摘要:

Compartment models are widely used in pharmaceutical research to quontitate the kinetics of absorption, distribution, metabolism and excretion of a drug. In this article two applications of the two compartment open model are discussed. This discussion shows that, in spite of the extreme simplification and obvious weaknesses of this model, it has properties that make it a useful tool in drug research when properly used.

摘要:

The principle of minimum discrimination information estimation is described and used to generate estimates for tests of hypotheses concerning various interactions and effects in the analysis of multidimensional contingency tables. All classical hypotheses for contingency tables can be generated by the use of this principle when certain marginals are considered as fixed. Analysis of information tables are given for a four-way contingency table.
