CESM Procedure

After the model parameters are estimated, one-step-ahead forecasts are generated for the full range of the accumulated and optionally transformed time series data, and multistep forecasts are generated from the end of the time series to the future time period that is specified in the LEAD= option in the PROC CESM statement. If there are missing values at the end of the time series, the forecast horizon will be greater than that specified by the LEAD= option.
