compute_tfce

A matrix of permuted statistical signal. The first row indicating the observed statistics.

distribution

A character string indicating the alternative hypothesis. Default is <code>"greater"</code>. Choose between <code>"greater"</code>, <code>"less"</code> or <code>"two.sided"</code>.

alternative

A scalar that represent the extend parameter of the TFCE transformation. Default is <code>E = 0.5</code>.

A scalar that represent the height parameter of the TFCE transformation. Default is <code>H = 1</code>.

The number of terms in the approximation of the integral.

Compute the TFCE correction given a matrix a permuted statistical signals.

Functions to compute p-values based on permutation tests. Regression, ANOVA and ANCOVA, omnibus F-tests, marginal unilateral and bilateral t-tests are available. Several methods to handle nuisance variables are implemented (Kherad-Pajouh, S., & Renaud, O. (2010) <doi:10.1016/j.csda.2010.02.015> ; Kherad-Pajouh, S., & Renaud, O. (2014) <doi:10.1007/s00362-014-0617-3> ; Winkler, A. M., Ridgway, G. R., Webster, M. A., Smith, S. M., & Nichols, T. E. (2014) <doi:10.1016/j.neuroimage.2014.01.060>). An extension for the comparison of signals issued from experimental conditions (e.g. EEG/ERP signals) is provided. Several corrections for multiple testing are possible, including the cluster-mass statistic (Maris, E., & Oostenveld, R. (2007) <doi:10.1016/j.jneumeth.2007.03.024>) and the threshold-free cluster enhancement (Smith, S. M., & Nichols, T. E. (2009) <doi:10.1016/j.neuroimage.2008.03.061>).
