On the Construction of a Parameter Orthogonal to the Mean
本文证明了许多参数族中参数与均值正交的条件具有简单形式，从而可以解析地得到显式正交参数，并为其他模型给出了正交参数化方法。
It is shown that for many parametric families the condition for a parameter to be orthogonal to the mean takes on a particularly simple form. As a result, it is often possible to obtain analytically an explicit orthogonal parameter, thus providing insight into the many situations involving parametric families in which such a parameter is known to exist. Orthogonal parameterizations are then given for some other models.
