The X11 Procedure |
See "Prior Daily Weights and Trading-Day Regression" in the "Details" section later in this chapter for details and examples using the PDWEIGHTS statement.
Each day=w option specifies a weight (w) for the named day. The day can be any day, Sunday through Saturday. The day keyword can be the full spelling of the day, or the three letter abbreviation. For example, SATURDAY=1.0 and SAT=1.0 are both valid. The weights w must be a numeric value between 0.0 and 10.0.
The following is an example of a PDWEIGHTS statement.
pdweights sun=.2 mon=.9 tue=1 wed=1 thu=1 fri=.8 sat=.3;
Any number of days can be specified with one PDWEIGHTS statement. The default weight value for any day that is not specified is 0. If you do not use a PDWEIGHTS statement, the program computes daily weights if TDREGR=ADJUST is specified. Refer to U.S. Bureau of the Census (1967) for details.
