The first post hoc, the LSD test. T he original solution to this problem, developed by Fisher, was to explore all possible pair-wise comparisons of means comprising a factor using the equivalent of multiple t-tests. This procedure was named the Least Significant Difference (LSD) test. The ...

方差分析中的Post-hoc检验 Post Hoc Tests in AN OVA This handout provides information on the use of post hoc tests in the Analysis of Variance (ANOVA). Post hoc tests are designed for situations in which the researcher has already obtained a significant omnibus F-test with a factor that cons...
Another approach to post-hoc testing is to use pairwise signed-ranks tests. In this case, we choose thePairwise Signed Ranksoption in Figure 1 ofFriedman Test Data Analysis Toolfor the signed-ranks tests using the normal approximation or thePairwise Exactoption to perform pairwise signed-ranks...

It is hoped that this article will lead to greater understanding of what post hoc power is—and is not. We also present a "grand unified formula" for post hoc power based on a reformulation of the problem, and a discussion of alternative views. 展开 ...
scikit-posthocs is a Python package that provides post hoc tests for pairwise multiple comparisons that are usually performed in statistical data analysis to assess the differences between group levels if a statistically significant result of ANOVA test has been obtained. scikit-posthocs is tightly...
