Combined Neyman-Pearson Chi-square: An Improved Approximation to the Poisson-likelihood Chi-square

Xiangpan Ji, Wenqiang Gu, Xin Qian +2

We describe an approximation to the widely-used Poisson-likelihood chi-square using a linear combination of Neyman's and Pearson's chi-squares, namely "combined Neyman-Pearson chi-…
