P-Value Precision and Reproducibility.
P-values are useful statistical measures of evidence against a null hypothesis. In contrast to other statistical estimates, however, their sample-to-sample variability is usually not considered or estimated, and therefore not fully appreciated. Via a systematic study of log-scale p-value standard errors, bootstrap prediction bounds, and reproducibility probabilities for future replicate p-value...
متن کاملThe reproducibility of research and the misinterpretation of p-values
We wish to answer this question: If you observe a 'significant' p-value after doing a single unbiased experiment, what is the probability that your result is a false positive? The weak evidence provided by p-values between 0.01 and 0.05 is explored by exact calculations of false positive risks. When you observe p = 0.05, the odds in favour of there being a real effect (given by the likelihood r...
متن کاملAsymptotics for p-value based threshold estimation in regression settings
We investigate the large sample behavior of a p-value based procedure for estimating the threshold level at which a regression function takes off from its baseline value – a problem that frequently arises in environmental statistics, engineering and other related fields. The estimate is constructed via fitting a “stump” function to approximate p-values obtained from tests for deviation of the r...
متن کاملThreshold estimation based on a P -value framework
We use p–values as a discrepancy criterion for identifying the threshold value at which a regression function takes off from its baseline value – a problem that is motivated by applications in dose-response studies, astronomy and engineering. In this paper, we study the problem in a controlled sampling setting, where multiple responses, discrete or continuous, can be obtained at a number of dif...
متن کاملThe Value of p-Value in Biomedical Research
Significance tests and the corresponding p-values play a crucial role in decision making. In this commentary the meaning, interpretation and misinterpretation of p-values is presented. Alternatives for evaluating the reported evidence are also discussed.
