One-way PerMANOVA in Past | Statistics Bio7

Описание: In this video tutorial, I will show you How to Calculate a One-way PerMANOVA by using the Past 4.06b version.

One-way PerMANOVA in Past Statistical Software

PerMANOVA (Permutational MANOVA, also known as NPMANOVA) is a non-parametric test of significant difference between two or more groups, based on any distance measure. PerMANOVA is normally used for ecological taxa-in-samples data, where groups of samples are to be compared, but may also be used as a general non-parametric MANOVA.
Items go in rows, variates in columns, and groups should be specified with a group column.

PerMANOVA calculates an F value in analogy with ANOVA. In fact, for univariate data sets and the Bray-Curtis distance measure, PerMANOVA is equivalent to ANOVA and gives the same F value. See the Past manual for mathematical details.

The significance is computed by permutation of group membership, with 9,999 replicates (can be changed by the user).

Pairwise tests

Pairwise PerMANOVAs between all pairs of groups are provided as a post-hoc test. Significant comparisons (at p 0.05) are shown in pink. The Bonferroni correction shown in the upper triangle of the matrix multiplies the p values with the number of comparisons. This correction is very conservative (produces large p values).
