摘要:

Abstract This paper discusses a numerical planning model for the bank notes operations at a central bank. The operation of the model is demonstrated by four examples taken from the present day situation in the Netherlands. The major aim of this effort has been towards developing a new tool for the assessment of the performance of the bank note process from a central banker's point of view. Thus the thrust has been towards the description of the bank notes operations at a central bank, utilizing a comprehensive quantitative model. In a sense, this effort exemplifies long‐term corporate planning of a central bank's issue departm

摘要:

Abstract This article presents a variant of the usual ratio and product methods of estimation, with the intention 10 improve their efficiency. The first order large sample approximations to the bias and the mean square error of the proposed estimator are obtained and compared with those of the well‐known methods (simple expansion, ratio, product, difference and linear regression methods). For a special case, the accuracy of the first order approximation (terms up to the ordern‐1) is examined by including terms upto the ordern‐2. With suitable choice of a design parameter, the proposed estimator turns out to be superior to the three methods mentioned first. The relation to the other two methods is examined; if the design parameter can be chosen near to the optimal value, the proposed method is seen to be approximately as efficient as the linear regression estimator. Finally some extensions are in

摘要:

Abstract In sample surveys the ratio (product) method of estimation is quite effective when there is a positively (negatively) high correlation between the study variate and an auxiliary variate on which supplementary information is available. This paper considers four estimators suited for cases where these correlations are only moderate and gives a rule of thumb for choosing among these and the traditional estimators. Such a choice needs a good guess of the interval containing a certain parameterk, which may not be hard in survey practice. A numerical example has been included for the case of positive correlation for illustration. An extension for using multiauxiliary information is also considere

Abstract The tables for the Friedman rank‐test arc extended using a sampling method. A table is given for the traditional significance levels .01, .025, .05 and .10 for number of blocks equal to 7 and 8 and for treatments of size 6 and 7. A brief discussion of available tables is also included along with an example of an applicat
