Saddlepoint approximations to score test statistics in logistic regression for analyzing genome-wide association studies
Johnsen, Pål Vegard; Bakke, Øyvind; Bjørnland, Thea; DeWan, Andrew Thomas; Langaas, Mette (Peer reviewed; Journal article, 2023)We investigate saddlepoint approximations of tail probabilities of the score test statistic in logistic regression for genome-wide association studies. The inaccuracy in the normal approximation of the score test statistic ...
