摘要:

* A paper read in Atlantic City, September 11, 1957, at a joint meeting of the American Statistical Association and the Institute of Mathematical Statistics. The chief source of biographical information was the 170 page memoir by Egon S. Pearson,Karl Pearson, An Appreciation of Some Aspects of His Life and Works, Cambridge University Press, 1938. Quotation has also been made from a paper by S. S. Wilks, “Karl Pearson: Founder of the Science of Statistics,”The Scientific Monthly, 53 (1941), 249–53 and from a Centenary Lecture by J. B. S. Haldane delivered at University College, London, on May 13, 1957 entitled “Karl Pearson, 1857–1957,” the text of which will be published inBiometrikain the near future.

摘要:

Diffusion indexes measure the extent of common participation of the various sectors of the economy in expansions and contractions of aggregate activity, and are used to study the relationships between the degree of participation and other characteristics of business cycles, such as turning points and amplitudes. The usual index takes account only of the direction of change of the components. An experiment was under-taken to determine if the behavior of a diffusion index of employment would be affected when it was weighted to allow for the size of the component industries, the amplitudes of the individual fluctuations, or the combined influence of size and amplitude. Size weighting made little difference, because the average size of industries in the expanding and contracting groups remained fairly constant despite substantial fluctuations over time in the number of industries contained in the two groups. Amplitude weighting exaggerated the month-to-month movements of the unweighted index, because the forces which made for an increase of diffusion also tended both to amplify the average increases in rising industries and to dampen the average declines in falling industries. The economic implications of the findings are discussed and several suggestions are offered about the use of diffusion indexes in the search for the causes of business cycles.

摘要:

The earliest preliminary or provisional estimates of sixteen items in the national accounts of the United States have been compared with the most thoroughly revised estimates currently available for the period, 1947 II-1955 IV. For corresponding revised and provisional estimates, average absolute differences in level and in amount of quarterly change have been calculated. Also the frequency of disagreement on direction of quarterly change has been determined. The results of these calculations have been reviewed in the contexts of two postwar business cycles and with reference to the methods of estimation employed by the Department of Commerce.

摘要:

Seasonal variation in consumption presents practical and theoretical problems when index numbers of price change are placed in series. Traditional formulas using varying seasonal weights for measurement from one month to the next will not yield satisfactory measures from year to year. This article describes a new type formula based on varying seasonal weights for month-to-month measurements which does not exhibit the “biases” of chain indexes and which satisfies classical index theory with respect to year-to-year comparisons. Results of statistical experimentation with alternative formulas are presented.

摘要:

The Philippines has embarked on a comprehensive program of statistical development. The main survey device employed is the Philippine Statistical Survey of Households which is producing vitally needed data for planning and administration. Operating and conceptual problems experienced may be similar to those in existence in other countries of like economic and social characteristics.

摘要:

The problem considered is estimation of the mean value of a character for a finite population, making use of information on an auxiliary character. A comparison is made between theppsestimate and the simple average, ratio and regression and stratified sample estimates. The results are obtained under the assumption that the finite population is a random sample from an infinite population possessing certain properties.
