统计和系统不确定性的同时最小二乘处理
Simultaneous Least Squares Treatment of Statistical and Systematic Uncertainties
摘要：
我们提出了一个最小二乘法估计参数的测量事件产额存在的背景和交叉馈电。我们采用一种统一的方法，将统计和系统的不确定性的实验测量输入到适合。我们用e+e- -> π（3770）-> D \bar D$跃迁中测量的绝对强子D介子分支分数来证明这种方法。
英文摘要：
We present a least squares method for estimating parameters from measurements of event yields in the presence of background and crossfeed. We adopt a unified approach to incorporating the statistical and systematic uncertainties on the experimental measurements input to the fit. We demonstrate this method with a fit for absolute hadronic D meson branching fractions, measured in e+e- -> ψ(3770) -> D\bar D$ transitions.
