threecity: threecity data
Description
Extracted data from a french population based cohort (Three-City cohort). The dataset includes
followup information on dementia outcome and predicted 5-year risks based on
based on the subject specific information which includes age, gender,
education level and cognitive decline measured by a psychometric test
(Mini Mental State Examination). The prediction model from which the
predictions have been computed has been fitted on independent training
data from the Paquid cohort, another french population based cohort with similar design (see Reference Blanche et al. 2015 for details) .
Format
A subsample consisting of 2000 observations on the following 3 variables.
- pi
- 5-year absolute risk predictions of dementia.
- status
- 0=censored, 1=dementia, 2=death dementia free
- time
- time to event (i.e., time to
either dementia, death dementia free or loss of follow-up)
