Significance Testing and Confidence Intervals
probabilities, it can be determined that combining the probability values of 0.11 and 0.07 results in a probability value of 0.045. Therefore, these two nonsignificant findings taken together result in a significant finding. Although there is never a statistical basis for concluding that an effect is exactly zero, a statistical analysis can demonstrate that an effect is most likely small. This ...
متن کاملThe Physical Significance of Confidence Intervals
We define some appropriate statistical quantities that indicate the physical significance (reliability) of confidence intervals in the framework of both Frequentist and Bayesian statistical theories. We consider the expectation value of the upper limit in the absence of a signal (that we propose to call “exclusion potential”, instead of “sensitivity” as done by Feldman and Cousins) and its stan...

متن کاملThe statistical and physical significance of confidence intervals
It is shown that the necessity to choose a specific Frequentist method, among several available, for the analysis of experimental data does not introduce any degree of subjectivity from a statistical point of view. However, the physical significance of confidence intervals obtained with different methods is different. Considering the case of a Poisson process with known background, we show that...
متن کاملHeuristic Confidence Intervals for the Gamma Test
The Gamma test is a fast non-parametric algorithm for estimating the noise variance in an input/output dataset modulo the best smooth model. In this short note we communicate a heuristic method for computing confidence intervals for the noise estimate returned by a Gamma test analysis.
