padCohortStart() Adds (or subtracts) a certain number of days to the cohort +end date. Note:

  • If the days added means that cohort end would be after observation +period end date, then observation period end date will be used for cohort +exit.

  • +
  • If the days added means that cohort exit would be after the next cohort +start then these overlapping cohort entries will be collapsed.

  • +
  • If days subtracted means that cohort end would be before cohort start then +the cohort entry will be dropped.
