The OUTSPAN= option is specified in the PROC statement, and writes the sliding spans results to the specified output data set. The OUTSPAN= data set contains the following variables:

• A1, a numeric variable that is a copy of the original series truncated to the current span. Note that overlapping spans will contain identical values for this variable.

• C18, a numeric variable that contains the trading-day factors for the seasonal adjustment for the current span

• D10, a numeric variable that contains the seasonal factors for the seasonal adjustment for the current span

• D11, a numeric variable that contains the seasonally adjusted series for the current span

• DATE, a numeric variable that contains the date within the current span

• SPAN, a numeric variable that contains the current span. The first span is the earliest span—that is the one with the earliest starting date.

• VARNAME, a character variable containing the name of each variable in the VAR list. A separate sliding spans analysis is performed on each variable in the VAR list.
