Demo Data
demo_data.RdA completely made up demo data set meant to mimic the structure of the NACC data. While IDs look like valid NACC IDs, these are simply the characters "NACC" with six random digits. Similarly, birth and visit dates are randomly created, and so are all scores with the only constraint that -4's are believable. (For example, if OTRAILA is -4, so is OTRAILB.)
