Beyond P-value: The Rigor and Power of Study

Fengyu Zhang, Claude Hughes

2019/12/25

There have been a series of recent discussions and debates on the p-value and statistical significance. These discussions, including publications of more than 40 papers in a special issue of the American Statistician, provide an excellent opportunity to think about some technical measures for practical implementation in grant applications and publications. While several factors have been discussed, it may be the rigor of a study that determines the p-value for reporting study results and judging a consistent replication of research. Based on the Fisherian and Neyman-Pearson theory,  we propose new criteria, which can be implemented without fundamental changes in existing statistics, to reduce false positives and irreplicability of studies that are either inadequately powered or overpowered.
