A Simple Confidence Interval for the Median
Large sample confidence intervals often have the form Dn ± z1−α/2 SE(Dn) whereDn is an estimator of the parameter and P (Z ≤ zα) = α when Z has a normal N(0,1) distribution. Replacing z1−α/2 by tp,1−α/2 can be viewed as multiplying z1−α/2 SE(Dn) by a finite sample correction factor tp,1−α/2/z1−α/2 in order to improve the performance of the interval for small sample sizes. This technique is used...
متن کاملConfidence Intervals and Hypothesis Testing.∗
If you have just two discrete hypotheses, then a hypothesis test is simply an application of Bayes’ Theorem. You check to see whether your data can reasonably be explained by that boring old null hypothesis (conventionally called H0), or not. To test H0, you need to compare it to one other model. One never tests a hypothesis in isolation; it is tested against an alternative (typically called H1...
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 کاملTempo Estimation for Music Loops and a Simple Confidence Measure
Tempo estimation is a common task within the music information retrieval community, but existing works are rarely evaluated with datasets of music loops and the algorithms are not tailored to this particular type of content. In addition to this, existing works on tempo estimation do not put an emphasis on providing a confidence value that indicates how reliable their tempo estimations are. In c...
متن کاملVisual Hypothesis Testing with Confidence Intervals
A simple visual method of comparing means given normal %~. confidence intervals is proposed. Monte Carlo simulations were used to derive a visual rule of thumb that can be used to test the null hypothesis of equal means, given the confidence intervals of the means, and the sample sizes (or degrees of freedom). The type-1 error rate of the test is approximately .05. The rule involves accepting t...
