Bartlett's Bias Correction to the Profile Score Function is a Saddlepoint Correction
本文证明了在规范指数族中，Bartlett对剖面得分函数的偏差修正与条件得分函数的双鞍点近似的前导修正项相等。
Bartlett's bias correction to the profile score function is proved equal, to first order, to the leading correction term of the double saddlepoint approximation to the conditional score function in canonical exponential families.
