متن کاملSignificance 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 کاملConfidence Intervals and Hypothesis Tests
Overview: Recall that a point estimator for a parameter of interest is a statistic which is a function of the random variables from which our sampling method chooses values. The properties of such an estimator, such as having a small bias or a small mean square error, are usually dependent only upon certain features of the sampling distribution of the statistic, such as its mean or variance. Ho...
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 کاملInterpretation of Bayesian " Confidence " Intervals for Smootidng Splines
A frequency interpretation of Bayesian "confidence" intervals for smoothing splines. Abstract The frequency properties of Wahba's Bayesian "confidence" intervals for smoothing splines are investigated by a large sample approximation and by a simulation study. When the coverage probabilities for these pointwise confidence intervals is averaged across the observation points, we explain why the av...
