MISSING Subcommand (TSAPPLY command)

The MISSING subcommand controls the handling of user-missing values.

  • By default, user-missing values are treated as missing (invalid) data.
  • System-missing values are always treated as invalid.
  • Cases with missing values of a dependent variable that occur within the estimation period are included in the model. The specific handling of the missing value depends on the estimation method.
  • For ARIMA models, a warning is issued if a predictor has any missing values within the estimation period. Any models involving the predictor are not reestimated.
  • If any predictor has missing values within the forecast period, the procedure issues a warning and forecasts as far as it can.
