摘要:

If a fixed number of observations are made sequentially, the outcome of a statistical test based on the complete sample sometimes can be anticipated by employing the following procedure: As each observation is made calculate least upper and greatest lower bounds for any subsequent value of the statistic; if the critical value does not lie between these bounds then the outcome of the test is determined and experimentation is terminated.

摘要:

Under certain assumptions two probability distributions for the variation in the number of births per couple are derived. A procedure to find the B.A.N. (Best Asymptotically Normal) estimates of the parameters of the first model is outlined. The distribution is applied to two examples.

摘要:

Goodman's simplified runs test is examined as a test for serial correlation and is found to be both much quicker to apply than other available tests and to be appropriate for use with non-stationary data provided that the series has no trend in mean. Approximations to the power of the test are discussed and it is found that the power is acceptable for samples of size 100 or more. Particular consideration is given to the application of the test to economic data.

摘要:

In this paper a brief review is given of some important developments in the theory of sampling from finite populations during the decade 1950–60. More specifically different selection procedures and estimators in sampling with varying probabilities and in ratio method of estimation, method of optimum stratification and assessment of non-sampling errors have been covered in this review together with some general techniques of improving upon certain types of estimators.

摘要:

Freund, Vail, and Ross [2], Goldberger and Jochems [3], and Goldberger [4] have given some results for the stepwise estimation of the parameters of a univariate regression model. We give here similar results for a multivariate linear regression model.

摘要:

The demographic model demonstrated in the following was designed to estimate fertility among women of a given age by order of birth of child. Estimations as to age-specific and age-order specific birth rates were made using three basic parameters that define the statistical structure of the model in terms of age limits of the female reproductive span and the maximum age-specific, or age-order specific, birth rate.

摘要:

A traditional proposition about the consumer demand for durables is that the effect of the initial stock of a durable upon new purchase of that durable is negative—the inventory effect. This paper examines, through a study of the demand for automobiles, the proposition that the effect of initial stock is a mixture of three effects: the inventory effect, the taste effect, and the trade-in effect. The paper concludes with a statement of findings (1) that such effects do exist and (2) that a more rigorous treatment of these effects than appeared in the literature is called for.

摘要:

Several discriminant and multiple regression analyses were performed on retail credit application data to develop a numerical scoring system for predicting credit risk in a finance company. Results showed that equal weights for all significantly predictive items were as effective as weights from the more sophisticated techniques of discriminant analysis and “stepwise multiple regression.” However, a variation of the basic discriminant analysis produced a better separation of groups at the lower score levels, where more potential losses could be eliminated with a minimum cost of potentially good accounts.

摘要:

Product diversification, in many cases, involves no quality improvement in the ordinary sense of the word and merely consists of an increase in the number of colors, sizes, and shapes in which an article is offered to the consumer. Nevertheless, such product-line extensions have cost-of-living implications. These are not obvious and seem to have been overlooked by writers dealing with the problem of incorporating quality changes into the Consumer Price Index. It is the purpose of the present paper to rectify this omission.
