I have three groups (one control and two tests), but with unequal group size.
I want to compare the two tests (A2 & A3) with the control (A1). To do this, I have
tried to perform the 'Shared control' but during the analysis process I get the
following message (
and the analysis is interrupted
): "Oops! Something went wrong..."
Somebody could help me?
I attach my dataset
Many thanks in advance
Regards
Pedro
