Imputation and derivation

Imputation

That date was computed for OUT Migration form as well as for Phase 1 Transfers-Out/Lost-to-follow ups forms being considered as an Out-Migration (cf. documentation of Exits dataset explaining how phase 1 forms have been manually recoded). According to the type of form, VP*Date could refer to VPOUTDate, VPTRODate or VPLFUDate. When VP*Date was incomplete or missing, or when this date was inconsistent (i.e. after VisitDate), a new date was randomly generated within a window taking into account: - Year and/or month if available in VP*Date - Date of the last visit in a previous survey round in the same household - A maximum window of 6 months (except if month was supplied in VP*Date) - Date of the last contact at home during that window (if any) To identify when that date was imputed, please look at ExitDateComputedEstimated variable

Others

Notes

(i) if exit date was missing or (ii) the year of the exit date was unknown or (iii) exit date was after VisitDate, then VisitDate (the date the exit from has been completed) was used instead of the exit date.
