WebbJoining a SAS® data set with an external database is a relatively common procedure in research, and there are several methods to improve its performance. If only one external database table is involved, and the join is an inner join, using the dbkey data set option should be quick and easy. The second method is WebbDefault Interpolation Method in PROC EXPAND: The Cubic Spline Function . 3 In nautical terms, a “spline” is a knot that is tied to join two pieces of rope. Mathematically, a “spline function” joins two (or more) segments of a time series, ...

WebbTo specify endpoint constraints, use the following form of the METHOD= option. METHOD=SPLINE ( constraint < , constraint > ) The first constraint specification applies to the lower endpoint, and the second constraint specification applies to the upper endpoint. If only one constraint is specified, it applies to both the lower and upper endpoints. WebbJoin or sign in to find your next job.
