All affected conditions will be removed after changing values in the table. So, finalize the table before. ...pairwise deletion \ available case method In contrast with listwise deletion, the available case method uses all available observations. That is, if a feature/variable for an observation is missing, a method or technique that uses this discards only the variable with missing information and not the entire observation.

Indeed, when we analyzed the PCR efficiency by standard method and Pairwise Efficiency method in case of 10-times dilutions, the efficiency values themselves were slightly different (Additional file 1: Table S10). The difference observed between the efficiency values in the 2-times and 10-times diluted series may be due to such a systematic ...

This coefficient can be used to quantify the linear relationship between two distributions (or features) in a single metric. It ranges from -1 to 1, -1 being a perfect ...If only pairwise comparisons are made, the Tukey method will produce the narrowest confidence intervals and is the recommended method. The Bonferroni and Scheffé methods are used for general tests of possible contrasts. The Bonferroni method is better when the number of contrasts being tested is about the same as the number of factor levels.

Compute the distance matrix from a vector array X and optional Y. This method takes either a vector array or a distance matrix, and returns a distance matrix. If the input is a vector array, the distances are computed.

Bonferroni Method. Bonferroni method for \(g\) comparisons – use \(\alpha / g\)instead of \(\alpha\) for testing each of the \(g\) comparisons. Comparing the Bonferroni Procedure with the Fishers LSD. Fishers’s LSD method is an alternative to other pairwise comparison methods (for post ANOVA analysis).
