Clustering of Microarray data via Clique Partitioning 总被引:2,自引:2,他引:0

Microarrays are repositories of gene expression data that hold tremendous potential for new understanding, leading to advances in functional genomics and molecular biology. Cluster analysis (CA) is an early step in the exploration of such data that is useful for purposes of data reduction, exposing hidden patterns, and the generation of hypotheses regarding the relationship between genes and phenotypes. In this paper we present a new model for the clique partitioning problem and illustrate how it can be used to perform cluster analysis in this setting. 相似文献

This paper replaces the competitive bidding models of Friedman and Gates with a more general probabalistic bidding model which resolves the conflict between them. The validity of the model is demonstrated by simulation. Practical difficulties of using the probabalistic approach are discussed and several lines of future research suggested. 相似文献

A test is proposed which requires a better fit in the extremes of a distribution than the Kolmogorov-Smirnov test for H0. not to be rejected. Critical values are calculated for sample sizes up to 100, and approximate critical values are found for larger samples. The power of the test is obtained for a number of distributions, and it is shown that the test is more powerful than some existing tests for a wide range of cases 相似文献

Participatory evaluation research empowers the consumers of services to become leaders in evaluation and change. Participatory research methods have been used widely in developing countries and are consistent with family therapy's recent emphasis on non-hierarchical, empowering, collaborative therapies. In this paper, the authors present several examples of participatory evaluation methods and discuss their applicability to the work of family therapists. 相似文献

In this paper, individuals’ desire to work more or less than they actually do (hours constraints) is analysed in nine OECD countries using data from the 1989 International Social Survey Program (ISSP). Our results show that hours constraints deviate substantially from country to country. However, in all countries, the proportion of individuals wanting to work more (and earn more) than they actually do is larger than the fraction of workers wanting to work less (and earn less). Socio‐economic and demographic characteristics, work attitudes, and work conditions have a significant effect on hours constraints. 相似文献

Many developing regions are facing a youth bulge, meaning that young people comprise the highest proportion of the population. These regions are at risk of losing what could be a tremendous opportunity for economic growth and development if they do not capitalize on this young and economically productive population, also referred to as the “demographic dividend,” defined as the increase in economic growth that tends to follow increases in the ratio of the working‐age population – essentially the labor force – to dependents. Nations undergoing this population transition have the opportunity to capitalize on the demographic dividend if the right social, economic, and human capital policies are in place. In particular, Sub‐Saharan Africa, the Middle East, and North Africa are at risk of losing the demographic dividend. These regions face high youth unemployment, low primary school completion, and low secondary school enrollment. This results in an undereducated and unskilled segment of the population. The prohibitive costs of education prevent young people from finishing school, thereby entering the labor market unprepared. This article presents a case for youth‐focused financial inclusion programs as one of the antidotes to the masses of poor, undereducated, and low‐skilled young people swelling the labor markets of poor developing countries. 相似文献
