Hello!
I see that I can export covariates, my opt out experiment, and my forced experiment in separate files. I want to export my survey data in just one file. Is that possible to do?
SurveyEngine exports the choice data and covariate data separately to avoid an explosion of data with an automatic merge.
however joining the data is trivially easy in R - or similar
if you have 2 datasets (covariates and dce). The R command to merge is.
merged ← merge(covariates, dce, by = “RID”, all.x = TRUE)
This does a ‘left join’ which means that all the covariate data rows are retained - even if there are missing DCE rows - which is possible if the respondent abandons the survey before the DCE section.
