摘要:
SummaryVentilatory function is a measure of the amount of air a subject can breathe, and is widely used epidemiologically for screening against chronic respiratory disease. The two indices considered here, Forced Expiratory Volume (FEV) and Forced Vital Capacity (FVC), are larger in tall men and decline with age, relationships which are conventionally standardized for by using the multiple ilnear regression on age and height. This paper presents an alternative model:FEV=heightk.(c+d.age)which combines a proportional and a linear relationship. The model is fitted by maximum relative likelihood and is compared with the linear regression model using Edwards's Method of Support.The initial set of data shows that the proportional model is appreciably better supported than the linear model and that the parameterkis very close to 2. This is confirmed by re‐analysing nine studies of ventilatory function from all over the world involving over 11,000 men and women.The value of 2 forkis shown to be explicable in terms of the allometric relationship between ventilatory function and height, and their correlation. Ventilatory function is found to go as the fourth, not the third, power of height, and the invariance ofkto differences in age, sex or ethnic group follows on from this.A test is provided of the hypothesis that the two coefficientscanddin the proportional model differ between groups by the same multiplier, and it is concluded that on the whole they do.

摘要:
SummaryThe optimal control of a linearized econometric model of the UK economy is demonstrated without and with stochastic disturbances of the character that occurred over the sample data from which the model was estimated. The estimation methods, state vector realization, control algorithm and model are described. The quadratic optimization criterion is presented in terms of its partial derivatives, which are described as the “priorities” of a marginal improvement in each economic variable, thus offering the link needed with policy makers' own sense of priorities.

摘要:
SummaryHere the continuous analogue of the Generalized Waring Distribution is obtained. It is in general of Pearson's Type VI and the successive moments of the G.W. distribution and the corresponding Type VI become infinite for the same values of ρ. When both a → ∞ andk→ ∞ the continuous analogue takes the Type V form. Both in this case and the case when only one ofa, k→ ∞ the continuous analogue can be regarded as alimiting formof the distribution. Whenqa→ 1, ρ → ∞kremaining finite (aandkmay be interchanged), the continuous analogue orlimiting formbecomes Type III.Exceptions to the Type VI form occur in certain cases, when the point (a, k) is in the square 0

摘要:
SummarySeasonal‐adjustment procedures based on regression methods applied to a mixed additive–multiplicative model are described. The procedures are based on the traditional model of trend, seasonal and irregular components but instead of assuming that the seasonal is purely additive or purely multiplicative as in the usual methods of seasonal adjustment they permit the use of a mixture of additive and multiplicative components. Tests are developed which are intended to investigate whether a purely additive, a purely multiplicative or a mixed additive‐multiplicative model is required by the data. For the general case where both additive and multiplicative components are required, the seasonal component is assumed to consist of a seasonal pattern and a seasonal amplitude which are estimated separately. The trend is estimated using moving‐average filters and the seasonal component is fitted by means of a stepwise regression method applied to additive and multiplicative Fourier components. Two main computer programs have been developed, the first of which tests whether a purely additive, a purely multiplicative or a mixed additive‐multiplicative seasonal model is required; the second estimates the seasonal component and produces a seasonally adjusted series. The methods are applied to a number of unemployment series for several countries.

摘要:
SummaryThe aim of this paper is to develop approximate expressions for the standard errors of two alternative regression based or hedonic cost indices. These standard errors are then compared using a simulation approach and it is shown that a weighted form of index has a smaller standard error than that of an unweighted form, the ratio of the two standard errors being principally a function of the coefficient of variation of the costs being analysed.

摘要:
SummaryIn the social sciences, particularly in economics, many summaries of size distributions, such as the Herfindahl index, are used which are not based on statistical distribution theory. Each measure is regarded as a unique contribution. The present paper expresses the most common of thesead hocmeasures in terms of the moments of moment distributions, which are firmly rooted in distribution theory and which are well established in the small particle statistics of physics. That is, thesead hocmeasures are governed by the moments of the underlying size distribution and do not add to the knowledge provided by the classical statistical analysis of economic size distributions.
