A rotation scheme for a stratified multi-stage sample, discussed in this paper, was designed to statisfy the following conditions: (i) there is a constraint on the number of units that can be replaced in each round, and (ii) it is relatively inexpensive to increase the sample size gradually. An example of these conditions was observed in the development of a plan for measuring the accuracy of the billing process of a telephone company. Estimators of the population proportion of elements that possess a specified characteristic are also derived. Each estimator is a weighted average of the corresponding estimates based on the retained units from the original sample and on the new units, where the weight of the estimate based on the new units increases over time. While this rotation scheme is discussed in connection with the billing accuracy of a telephone company, the methodology can be applied to other similar problems. 相似文献

This paper considers a generalization of the exponential type distributions in the class of exponential families. A characterization and a method of generating an exponential family from a given family are given. In particular the generalized gamma, the generalized Poisson, the inverse Gaussian distributions belonging to this family are discussed. The approximations of the cumulative sums for the generalized gamma and the generalized Poisson by the Chi-square are considered. Some of the results are extended to the bivariate case. 相似文献

The concept of weighted distributions is well-known in the literature concerning observational studies and surveys in research related to forestry, ecology, bio-medicine and many other areas (cf. Rao (1965)). This paper extends the idea of weighted distributions to multivariate case. A few multivariate orderings have been defined and some partial ordering results are presented. Some results regarding multivariate positive and negative dependence are also discussed. Multivariate weighted distributions - joint, marginal and conditional have been defined and some important results concerning them are presented along with an illustration. The Multivariate Poisson Negative Hypergeometric Distribution has been derived. 相似文献

We give sufficient identifiability conditions for estimating mixing proportions in two‐component mixtures of skew normal distributions with one known component. We consider the univariate case and two multivariate extensions: a multivariate skew normal distribution (MSN) and the canonical fundamental skew normal distribution (CFUSN). The characteristic function of the CFUSN distribution is additionally derived. 相似文献

Adopting Aaker's (1997) framework, this study explored how popular tourist destinations, Mexico and Brazil, communicate their brand personality through Facebook, and which personality traits their Facebook “friends” associate with them. Results of computer-aided content analysis indicated that both countries’ tourism promotion messages emphasize distinct brand personality traits. However, Mexico's public relations efforts were more successful than Brazil's in transferring projected brand personality to its Facebook “friends”. 相似文献

This paper investigates the structure of the relationship between female education and fertility. It is based on data published in First Country Reports of the World Fertility Surveys for eleven countries—Costa Rica, Colombia, Dominican Republic, Panama, Fiji, Korea, Malaysia, Pakistan, Sri Lanka, Thailand, and Indonesia. The cumulative marital fertility of educated women is shown to be similar in different settings. A lack of uniformity in the education and fertility relationship including the curvilinear nature of this relationship observed across countries is shown to be attributable to marked differences between countries in the average fertility of women with no education rather than to the presumed differences in the average fertility of the educated women. The structure of the relationship is shown to be similar across several developing countries. This analysis suggests that advancement in female education can be expected to influence fertility behavior even without simultaneous changes in other factors such as increasing opportunity for participation in the paid labor force in the modem sector. 相似文献

Abstract In this paper reliable estimates of mean fecundability at marriage for a sample of heterogeneous Taiwanese women are obtained by using a set of data collected retrospectively. The effects of 'truncation bias' and 'memory bias' are estimated by studying the relationships between mean fecundability and the duration of marriage. Then the variations in fecundabilities by age at marriage are studied. The data are taken from an intensive fertility survey of married women between the ages of 20 and 39 conducted in Taichung city of Taiwan towards the end of 1962 prior to a year-long family planning action programme. Fecundability, the probability of conception in the absence of contraception, is estimated by using a Type I geometric model and is estimated from the observed distribution of first pregnancy intervals-the period between the onset of marriage and the beginning of first conception. The estimated fecundability level relatively free from truncation and memory bias is 195±3 per 1.000 women. The fecundability level increases with wife's age at marriage (up to 25) independently of its association with the duration of marriage. 相似文献

The ILO has developed an innovative concept of global solidarity for social security — the Global Social Trust — which supports the development of national social protection systems through international financing. The concept is ready to be tested nationally and the present paper proposes a pilot project for Ghana. The paper considers the virtues and weaknesses of developing-country social security healthcare systems and community-based voluntary insurance schemes, their lack of informal sector coverage on the one hand and their financial disequilibria on the other. It outlines the socio-economic and macro-policy context of Ghana and the current health policy environment. It argues for a fusion of the social health insurance and mutual health organization concepts in Ghana, thus linking community initiatives to national institutions, enhancing coverage and the quality of services for all. The paper outlines a basic model that could apply to Ghana, its organizational structure, practical functioning, financing arrangements and expected outputs. In particular it seeks to develop a model for the cross-subsidization of insurance premiums for the poor. It describes a concept that would combine local ownership initiatives with national responsibility and financing, arguing for a truly interrelated network of social protection. The authors welcome feedback and comments from the wider social security audience. 相似文献
