Multiple testing of interval composite null hypotheses using randomized p-values

Ochieng, Daniel - In: Statistical Papers 65 (2024) 8, pp. 5055-5076

behavior of the distribution function of the two p -values under the null hypothesis and alternative hypothesis for a fixed … significance level t∈(0,1)and varying sample sizes. We evaluate the performance of the two p -values in estimating the proportion …

Unlucky Number 13? Manipulating Evidence Subject to Snooping

Hassler, Uwe; Pohle, Marc‐Oliver - In: International Statistical Review 90 (2022) 2, pp. 397-410

Questionable research practices have generated considerable recent interest throughout and beyond the scientific community. We subsume such practices involving secret data snooping that influences subsequent statistical inference under the term MESSing (manipulating evidence subject to snooping)...

Important issues in statistical testing and recommended improvements in accounting research

Dyckman, Thomas R.; Zeff, Stephen A. - In: Econometrics 7 (2019) 2, pp. 1-11

Many financial decisions, such as portfolio allocation, risk management, option pricing and hedge strategies, are based on forecasts of the conditional variances, covariances and correlations of financial returns. The paper shows an empirical comparison of several methods to predict...
