In permuco: Permutation Tests for Regression, (Repeated Measures) ANOVA/ANCOVA and Comparison of Signals

permuco

This package provides functions to compute permutation tests in linear models with nuisances variables. The package has several goals :

• Providing to users the most recent methods to handle nuisance variables for permutation tests in the linear models.
• Giving to users tools to compute most common tests in linear model (t-test, ANOVA and repeated measures ANOVA).
• Providing an extension for the multiple comparisons problem in linear models with a focus for EEG data.

See Reference for more information on the function or check the article presenting the package.

The lmperm() function

This function is constructed as an extension of the the lm() function for permutation test. It produces t statistics with univariate and bivariate p-value by permutation.

The aovperm() function

This function is constructed as an extension of the the aov() function for permutation test. It produces marginal F statistics (type III) for factorial ANOVA and ANCOVA. Moreover, repeated measures ANOVA can be perform using the same notations used in an aov() formula with +Error(id/within) to specify the random effects.

The clusterlm() function

This function compute cluster-mass statistics for multiple comparisons. It is designed for ERP analysis of uni-channel EEG data. The left part of formula object must be a matrix or dataframe which columns represents multiple responses tested on the same experimental design (specified by right part of the formula). This function provides several methods to handle nuisance variables, a F or t statistics, an extension for repeated measures ANOVA and several methods for the multiple comparisons like the threshold-free cluster enhancement.
