摘要:
The accurate record of stock market ticker prices displays striking properties of dependence. We find for example that after a decline of 1/8 of a point between transactions, an advance on the next transaction is three times as likely as a decline. Further examinations disclose that after two price changes in the same direction, the odds in favor of a continuation in that direction are almost twice as great as after two changes in opposite directions.

摘要:
A practical computing technique is presented for the joint estimation of regression coefficients and the error spectrum in regression problems with stationary errors. In problems where unweighted least squares is not efficient, the procedure gives an estimate approaching the minimum variance linear unbiased estimate. Whether unweighted least squares is nearly efficient or not efficient, the procedure, in general, gives a much closer estimate of the covariance matrix of the estimated regression coefficients. The proposed approach, which involves the finite Fourier transformation of the observations and regression vectors, gives a useful intuitive understanding of the effects of correlated errors on regression.

摘要:
A simple test for recognising differences in mean is described. It has its origins in a test proposed by Tukey in 1959, and effectively ignores that piece of data which most seriously detracts from the significance of Tukey's statistic. Heuristic discussions and a reference to empirical evidence are given concerning the resultant improvement in power. The test is quick to execute both in formation of the statistic and in deciding on its significance, since in a wide class of situations the 5%, 1% and .1% critical values can be taken as 10, 13 and 17 respectively. Tables of critical values for small samples are however included, as are graphs based on asymptotic considerations.

摘要:
The general theory of the asymptotic power of chi square tests requires the evaluation of a non-centrality parameter which is expressed as a vector-matrix vector product. This parameter is evaluated for two of the models associated withr×ccontingency tables. This permits the power of such tests to be approximated on a large sample basis. Further considered are some implications of these results for sample design problems.

摘要:
The Stigler Committee Report [20, 21, 22] has stressed the desirability of revising the Consumer Price Index in the direction of a fixed-utility cost-of-living index. This paper proposes that a linear programming approach might be feasible for developing the food component price index of a cost-of-living index, and perhaps also for some other components. The main advantage of the linear programming approach would be that it recognizes substitutions among goods and services as prices change, whereas the conventional fixed market-basket approach to the formulation of index numbers makes no provision for such trading off of commodities and services.

摘要:
The Revenue Act of 1954 permitted entrepreneurs for the first time to make use of the double declining balance (DDB) and sum of the year's digits (SYD) methods of depreciation in place of the customary straight line method (SL). The tax advantages from using such methods are well known.1In spite of these advantages, however, the accelerated methods in many cases appear to have been adopted only slowly over the years. Clearly any attempt to determine the effect on investment of such provisions must rely on knowledge of the extent of their use. Unfortunately there is no direct information available, nor do estimates exist, for the two-digit manufacturing industries on the fraction of investment in each year since 1954 written off by accelerated methods. In this paper an attempt is made simultaneously to estimate such figures on an annual basis and to fit a learning curve to them.2

摘要:
This paper develops a stochastic model of accounts receivable, the debt arising from credit sales; and expresses the expectations and variances of (1) credit sales, (2) collections, (3) bad debts, (4) collections plus bad debts; and, (5) accounts receivable outstanding, in terms of parameters of the stochastic variables: (a) the number of credit sales made, (b) the size of sales; and, (c) the collection period or the effective term of loans. The paper discusses some interesting features of the results of the model and provides an empirical example to illustrate the model in context of actual credit sales made by a small wholesale food company during the years 1963 and 1964.

摘要:
Minimum variance unbiased estimators of reliability are developed for a series, parallel, and standby redundant system where the components are from a single exponentially distributed population. It is assumed that sampling information has been censored with respect to number of failures or test time.
