Hello,

I have some problems with the repeated anova.

Basically, I observed certain reactions of participants in my study: They have been presented with some form of default (an ethical or an unethical), and had the chance to reject or accept it. They repeated this procedure 11 times. While the default they have been shown is the same for every individual the whole time, the reaction of the individual can change. This leads to four possible groups: Accepting an ethical default, rejecting an ethical default, accepting an unethical default, rejecting an unethical default.
Besides the record of their decision, I measured the time they needed for their response.
Now I want to analyze if there is a difference between the time needed for the groups named above.
Doing some research I found that others used the repeated anova for this. I already reshaped my data into the long form, but now I'm a bit stuck.
I found many examples for the repeated anova with different treatments, but the treatments basically were the same over all points of time. In my case however, they might change. (the four groups i mendtioned)
Can anyone tell me if the following command is correct? Because I'm comparing reaction_times for only two possible times at once, I included the if (...), and as the decision might change i also added dropemtpycells
Thank you in advance.


anova completion_time_task3r reaction_task3r / index|reaction_task3r round reaction_task3r#round if reaction_task3r != 2 & reaction_task3r!=4, repeated (round) dropemptycells

completion_time_task3r: gives the time needed to respond
reaction_task3r : the possible reaction they could have (see above 1-4)
index: the number the participants have been given
round: gives the number of the repeated measurements (1-11)
