They are widely applied to economics, biomedicine, epidemiology, and so on. There are extensive studies on them in the latest three decade years. In this paper, many of models related to varying-coefficient models are gathered up. All kinds of the estimation procedures and theory of hypothesis test on the varying-coefficients model are summarized. Prom my opinion, some aspects waiting to study are proposed.展开更多

Led by that, the authors came up with the idea to examine the possibilities of the application of this principle within the courses of mathematics and music. This paper examines the relationship of correlation-integration-co-ordination, or linking-conjoining-harmonizing. The sample consists of the students at the fourth and fifth year of the Pedagogical Faculty in Sarajevo. The research topic is the correlation between mathematics and music. The research problem is the possibility to successfully realize a class in which mathematical and musical activities correlate. The aim of the research is to come up with some guidelines that would lead to a more successful application of the aforementioned correlation in practice. The conclusion is that we should work more on the possibilities of applying various forms of intercorrelation between subjects, to make the class content even more appropriate to the natural environment in which the child learns in a relaxed manner.展开更多
