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

1 code implementation17 Mar 2019 Xiangpan Ji, Wenqiang Gu, Xin Qian, Hanyu Wei, Chao Zhang

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-square" ($\chi^2_{\mathrm{CNP}}$).
