About the dataset

[刘朝]

hey guys! I just wonder what does the description of these three datasets means?

D1 - a comprehensive longitudinal data set for training;(means for training)

D2 - a comprehensive longitudinal data set on rollover subjects for forecasting;(what does "on rollover subjects for forecasting" means?)

D3 - a limited forecasting data set on the same rollover subjects as D2.(what does "rollover subjects" means?)

D2: "rollover subjects" is explained on the TADPOLE website, https://tadpole.grand-challenge.org/Details/

It's participants already in ADNI before ADNI3 who were eligible to roll over into ADNI3.
