<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">Dear list,<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">I have a variable 'X' with 29 × 1 values that tells me how strong the desired behavioural effect is.<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">And I have a matrix 'ITC_values' with 29 × 62 × 12 × 200 with EEG (ITC) values.<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">29 participants<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">62 channels<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">12 frequencies<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">200 time points<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">Could anyone suggest me an approach to find significant correlations between my EEG data and my behavioural data?<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;"><o:p> </o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">Addition:<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">I had the idea to calculate Mutual information<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">So, I calculated the Mutual information between<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">X and ITC_values(: , 1 , 1 , 1)<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">and<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">X and ITC_ values (: , 1, 1, 2)<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">and so on.<span class="Apple-converted-space"> </span><o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">In other words: I calculated the relationship between the hysteresis values and each timepoint at each frequency on each channel.<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">So, my result is a matrix with the size of 62 × 12 × 200 that holds all Mutual Information values.<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">Is this a valid approach?<o:p></o:p></div>
<div style="margin: 0cm; font-size: 11pt; font-family: Aptos, sans-serif;">Cause now I want to check the significance with a cluster permutation test. But that normally works only across subjects. But the MI values are already the result of aggregating participants.<o:p></o:p></div>
