1、 广义线性模型论文:广义线性模型中极大拟似然估计的相合性与渐近正态性【中文摘要】广义线性模型是一类非常重要的数学模型,是经典线性模型的推广,有着广泛的应运。在经济,社会,医学,生物等数据的统计分析上有这重要的意义。可以适用于连续数据与离散数据,尤其是后者,如计数数据,属性数据等等。广义线性模型包括线性回归,方差分析模型,交替响应的对数和概率单位模型模型,对数线性模型,计数的多项响应模型和生存数据的一些常用模型。以上这些模型具有大量的性质,例如线性性,我们可以使用这些性质得到很好的效果。除此之外,我们还有计算参数估计的常用方法。广义线性模型的个例起源很早,世界著名统计学家费舍尔曾于 1919 年
2、使用过该模型。1972 年 Nelder 和 Wedderburn 在一篇论文中引进了广义线性模型的概念。1989 年 McCullagh 和 Nelder 再版的著作详细的论述了广义线性模型及其取得的成果。时至今日,这方面的研究文献数以千计。本文研究了广义线性模型的参数估计,研究估计的渐近性,包括渐近存在性,相合性和渐近正态性。1.本文研究了在自适应设计和自联系情况下,广义线性模型极大拟似然的渐近存在性。当响应变量 yi 是q1 维,设计阵 Xi 是 pq 维且有界,以及最小特征根 sup E 以及其它正则条件下,证明了极大拟似然估计(MQLE)的渐近存在性,弱相合性和收敛速度。之前没有文献
3、在 n的条件下,获得相应的结果。2.本文研究了在自适应设计和自联系情况下,广义线性模型极大拟似 然的渐近正态性性。当响应变量 yi 是 q1 维,设计阵 Xi 是 pq 维且有界,及及其它的正则条件下,广义线性模型有一个渐近正态的根。这将高启兵和吴耀华(2004)中的条件减弱到了【英文摘要】The generalized linear model, which is the classical linear model promotion, is a kind of very important mathematical model and has been widely used.

There are massive properties in some models above, such as the linearity.
6、 We can use these properties to obtain the very good effect. In addition, we also have commonly used methods of the parameter estimation.Generalized linear models example originated very early. World-famous statistician Fish once used this model in 1919. In 1972 Nelder and Wedderburn introduced the
