Hi Folks,
I just discovered that my dataset (coming from QuestionPro platform) has got
multiple lines for each respondent id, but what I would really need is a
"regular" data matrix where each respondent's data is shown on a single line.
Does anyone has already develop a procedure that automatically takes the
multiple lines and aggregates them into a single line?
Thank you in advance,
Luca
