Estimation and testing of time-varying coefficient regression models in the presence of linear restrictions

A linear regression model with random walk coefficients is extended to allow for linear restrictions between the coefficients to be satisfied at each point in time. Estimation in this model is shown to be no more involved than estimation in the standard model. It is also demonstrated how, after a slight modification to the testing problem, classical test procedures may be applied to the problem of testing for such restrictions. The performance of the Lagrange Multiplier test for a variety of different restrictions is then investigated via simulation. An empirical application involving testing for homogeneity in a random walk coefficient version of the AIDS model is given.     

高等师范学生教师职业技能训练及培养模式新论

高等师范学生的教师职业技能训练,自国家1995年《教师资格条例》颁布以来,虽在全国有关高校一度出现好的势头,但很快被我国高校扩招的形势冲淡了,目前情况令人担忧。因此,在我国高等教育发展的新形势下,从宏观上构建高等师范学生教师职业技能培养模式应是当务之急。     

The Development and Application of Combined Thermoregulatory Mathematical Models

Thermoregulatory mathematical models have being developed for more than half a century and obtained more and more wide application. Among them, the "engineering-physiological" thermal models, which correlated closely to the man-machine-environment system, are the ones that developed most rapidly and have been widely accepted by thermal physiologists and environmental control engineers.This paper attempts to outline briefly the development and application of such kind of thermal models, discusses how to further develop and apply various combined thermal models in practice, and puts forward four respects of suggestions for establishment and modification of combined thermal models of man-clothing-cabin environment.     

催化重整生焦动力学模型的研究 I.生焦动力学模型的建立

在催化重整１６集总动力学模型的基础上,假设同类反应的失活函数是相同的,建立了生焦动力学模型。在排除了内外扩散等影响因素的前提下,确定了催速生焦失活反应条件和催化剂活性评价条件,使在实验室进行生焦动力学模型的研究成为可能。     

球对称动态黑洞的广义Stefan-Boltzmann定律

选取超前爱丁顿坐标，采用统计的方法，计算出动态黑洞的瞬时辐出度．结果表明，动态黑洞的瞬时辐出度不仅与假定黑洞处于热力学平衡时的辐出度有关，还与黑洞的事件视界速度、事件视界温度、事件视界附近的熵密度及黑洞的吸收和辐射系数有关．对于球对称动态黑洞，任一时刻黑洞的瞬时辐出度总是正比于黑洞事件视界温度的四次方．
