<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal>I’ve already looked at the 2007 JMN paper by Maris and
Oostenveld, but still have some remaining questions about using a vector-valued
test statistic to assess differences between 2 conditions (correct vs incorrect
memory task performance). I’ve attached a cluster map showing the many
different sizes and shapes that make it necessary to use a vector-valued test statistic.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>1)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Do the existing FT functions handle vector-valued stats?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Are all ClusterStats from each permutation (bigger than
a minimum size) included when constructing a multivariate permutation
distribution?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>3)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Are clusters of all sizes compared to the same
permutation distribution? I.e., would the 3<sup>rd</sup> largest cluster
be compared to a permutation distribution obtained from just the 3<sup>rd</sup>
largest stat from each permutation?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>4)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Our trials each have a baseline period – in order
to assess the differences between the two conditions, should we limit the permutation
distribution to stats selected just from the active periods of each
permutation?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thank you very much in advance!<o:p></o:p></p>
