<p class="MsoNormal">Hello everybody, <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I‘ve got a question in relation to the eeglab output. Does eeglab use the same computation of ANOVA and Bonferroni-correction like SPSS does? When I transfer the specdata from eeglab to SPSS and compute an ANOVA with post hoc tests in order
to get pairwise comparisons between my conditions, there were given significant differences. But in the pairwise comparison of the conditions in eeglab are not all electrodes significant like shown in SPSS.
