Inference in ecology and evolution.

Most ecologists and evolutionary biologists continue to rely heavily on null hypothesis significance testing, rather than on recently advocated alternatives, for inference. Here, we briefly review null hypothesis significance testing and its major alternatives. We identify major objectives of statistical analysis and suggest which analytical approaches are appropriate for each. Any well designe...

Commentary: Null points--has interpretation of significance tests improved?

Berkson's piece, 1 more than 60 years since its publication, is the author's struggle with questions of interpretation that still plague those conducting and interpreting statistical analyses today. Berkson seems to make little progress with solutions to the problems he presents, so it is of interest to see how statisticians today might deal with them. A P-value (significance level) is used to ...

Statistical inferences under the Null hypothesis: common mistakes and pitfalls in neuroimaging studies

Published studies using functional and structural MRI include many errors in the way data are analyzed and conclusions reported. This was observed when working on a comprehensive review of the neural bases of synesthesia, but these errors are probably endemic to neuroimaging studies. All studies reviewed had based their conclusions using Null Hypothesis Significance Tests (NHST). NHST have yet ...

The Problem Is Epistemology, Not Statistics: Replace Significance Tests by Confidence Intervals and Quantify Accuracy of Risky Numerical Predictions

Significance tests have a role to play in social science research but their current widespread use in appraising theories is often harmful. The reason for this lies not in the mathematics but in social scientists’ poor understanding of the logical relation between theory and fact, that is, a methodological or epistemological unclarity. Theories entail observations, not conversely. Although a th...
