Geographical and Time Imputation in a Macrotable. Applications to the EUSTAT Tourism Survey

E Goni, J Aramendi, M Bárcena, A Iztueta, F Tusell
For some time now, the users of EUSTAT have been raising new information demands for our Tourist Occupancy Survey. The survey design does not allow certain temporary and geographical disaggregation to be provided immediately. The initial sample design produces monthly estimates for geographical strata, based on a time sampling schedule. The methodological problem raised is how to obtain a total time and geographical disaggregation to answer any requests for estimates. The solution has been

We have chosen the method of the imputation to obtain the information relating to the missing data (due both to the sample design or to the total nonresponse), as it guarantees the consistency of the imputed values. In the paper we propose a hot-deck imputation procedure, more precisely, the nearest neighbor method. This choice ensures the effect of the geographical location on the occupancy.
