缺失数据广义估计方程中的完全随机缺失检验AI 解读

We consider inference from generalised estimating equations when data are incomplete. A test for missing completely at random is proposed to help decide whether or not we should adjust estimating equations to correct the possible bias introduced by a missing-data mechanism that is not missing completely at random. Likelihood ratio tests have been introduced to test the missing completely at random hypothesis (Fuchs, 1982; Little, 1988). For the estimating equation setting,…

二元响应曲线的序贯估计：一种新的估计方法AI 解读

This paper studies methode given by Wetherill (1963) for estimating general percentage points of a quantal response curve. A new method of estimation is proposed which is both simple to compute and highly efficient. The use of this with the Up and Down Transformed Reaponse Rule (UDTR) is investigated, by exact calculation of probability distributions and by empirical sampling trials. The use of the UDTR to estimate the slope of a response curve is outlined.
