Weibull distribution is widely used as a life distribution, and estimating lower confidence limit of reliability is important. But so far this problem has not been well solved if when the sample size is small.

威布尔分布是使用非常广泛的寿命分布，关于威布尔分布的可靠度的下限估计是一个有重要意义的问题，文献中有很多讨论，但当样本量较小时，关于二参数威布尔分布的可靠度的下限估计至今没有非常有效的方法。

In the first charpter,response variable is generalized to q dimensions, we propose the concept of QMLE and quasi function in nonlinear models, then under mild conditions, we prove that there exists the solution_n with probability 1 for sufficiently large n, and obtain the strong consistency, some results of asymptotic normality, meanwhile consistent estimator of σ~2 for QMLE for heterosedastic nonlinear models is presented.

在第一章中，我们首先将响应变量由一维推广到了多维，得出了非线性模型的极大拟似然估计的定义和拟似然方程，然后在一定的条件下，证明了当样本量n充分大时，拟似然方程以概率1有解？？_n且收敛于参数的真值(即定理1.2)，并且给出了极大拟似然估计的渐近正态性(即定理1.3，1.4)，最后考虑了异方差非线性模型的离差参数σ~2的相合估计(即定理1.5)。

We explore the determinants of debt placement structure by analyzing the Chinese market company' panel data for the periods from 2000 to 2004, the methods we choose include multiple linear regression model and contingency table test.

本文以2000-2004年沪市和深市的A股上市公司面板数据为研究对象，银行借款影响因素使用的普通多元线形回归模型，在公司债券影响因素方面由于样本量的限制，文章选择了列联表卡方检验。

The results indicate that intelligent is correlated with the double loop whorl, radial, simple creese hand, the third and fourth interdigital area pattern I3 and I4. The regression equations for predicting intelligent and radial, intelligent and I3, intelligent and I4 were calculated according to above results.

但是，多数学者所选用的实验对象为成人或优秀运动员，与早期实际选材相脱节，加之学者们的研究结果在某些指标上表现不尽相同和研究的样本量较小，误差较大等因素，使皮纹选材的理论体系尚不够完善。

Sampling frame – 100 consultant psychiatrists from Yorkshire Deanery; 100 schizophrenia trialists whose e-mail is publicly available; 100 RETHINK service users.

样本量及对象：100名来自Yorkshire Deanery精神科医生、100名从事精神分裂症研究的研究者（他们的电子邮件地址是面向大众公开的）、100名经过反复思考选取的"服务使用者"。

The total number of parts determined in Section 3.2 are to be subjected to the hydrogen embrittlement test.

做氢脆试验的样本量按3.2条来确定。

The probability to commit error is less thanα+2β×0.01. For enumeration data:According to the practical sample size and the relative magnitude between two sample proportions,a user can make an equivalence conclusion if the P value of difference test is equal to or larger than P_listed in the forms.

对于计数资料，用户可根据实际所用样本量、由试验结果所求出两样本率之间的相对大小关系以及差异性检验P值查表，若大于等于表中的P_，则可下等效性结论，犯错概率小于α+2β×0.01。
