Hi Bastien, You have three levels of hierarchy here: Level 3 is Groupe, which is not relevant for the moment. Level 2 is Participant. Level 1 is "recording."

sort Participant Phase Distance Répétition by Participant: gen recording =_n

local rec 1 forval p=1/2 { forval d=1/5 { forval r=1/8 { rename Erreur_Absolue`rec' Phase`p'Distance`d'Répétition`r' local rec `++rec' } } } Russell Dimond Statistical Computing Specialist Social Science Computing Cooperative University of Wisconsin-Madison On 11/30/2012 10:25 AM, Bastien Christian wrote:

I Nick, Thanks for your advice. I did look at the available help, but did non find an answer. Here is an example of the data : Groupe = Group (Réel, Augmenté) (between subject factor) (10 subjects per group) Participant = participant id Genre = Gender Age Phase (1 2) (within factor) Distance = (8 15 23 28 33) (within factor) Répétition : Repetition (1 2 3 4 5 6 7 8) (within factor) Erreur_Absolue = Abs(distance error) the dependent variable With this design, I get 800 recordings. For each subject, we have 80 recordings. Long Format: Groupe Participant Genre Age Phase Distance Répétition Erreur_Absolue Réel 1 Femme 27 1 8 1 0.1 Réel 1 Femme 27 1 8 2 0.0 Réel 1 Femme 27 1 8 3 0.1 Réel 1 Femme 27 1 8 4 0.0 Réel 1 Femme 27 1 8 5 0.0 Réel 1 Femme 27 1 8 6 0.1 Réel 1 Femme 27 1 8 7 0.0 Réel 1 Femme 27 1 8 8 0.0 Réel 1 Femme 27 1 15 1 1.8 Réel 1 Femme 27 1 15 2 0.2 Réel 1 Femme 27 1 15 3 0.0 Réel 1 Femme 27 1 15 4 0.4 Réel 1 Femme 27 1 15 5 0.4 Réel 1 Femme 27 1 15 6 0.0 Réel 1 Femme 27 1 15 7 0.2 Réel 1 Femme 27 1 15 8 0.1 Réel 1 Femme 27 1 23 1 0.4 Réel 1 Femme 27 1 23 2 1.0 Réel 1 Femme 27 1 23 3 1.2 Réel 1 Femme 27 1 23 4 0.2 Réel 1 Femme 27 1 23 5 0.6 Réel 1 Femme 27 1 23 6 0.4 What I would like to have : 1 line per participant Groupe, Participant, Genre, Age, Phase1Distance1Répétition1, …, Phase1Distance1Répétition8, Phase1Distance2Répétition1,…,Phase1Distance2Répétition8, …, Phase2Distance5Répétinion8 For the variables such as Phase1Distance1Répétition1 I would have As for the code, I just can't figure out the syntax. I tried to reshape with the dialogue box, but I always get an error message indicating that the Participant for example, is not unique within Groupe; there are multiple observations at the same Participant within Groupe. Hope this will help, Christian Bastien Le 30 nov. 2012 à 16:32, Nick Cox <[email protected]> a écrit :It is better to give a concrete example of what your data look like and to show code you tried on which we can comment.

My design use 1 between factor (Group{2}) and 3 repeated factors (Trials(8), Distance(5), Phase(2)). In fact the between factors allows the counterbalancing of the Phase Conditions. Thus, each participant goes through 2 phases. In each phase 5 target positions are used, and for each position there is 8 trials. The task consists in positioning a virtual object as near as possible to the target. We measure the distance between the virtual object and the target. I tried to use the "reshape" command but failed. I just can't handle the syntax for 3 repeated measure.* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
