OUTPATH= Data Set
The OUTPATH= data set records the path analysis between each INPUT and TARGET statement variable. This data set records the path sequences for each slide index and for each warp index associated with the slide index. The sequence values recorded are normalized and scaled based on the NORMALIZE= and SCALE= options.
The OUTPATH= data set contains the variables specified in the BY statement and the following variables:
- _INPUT_
-
input variable name
- _TARGET_
-
target variable name
- _TIMEID_
-
time ID values
- _SLIDE_
-
slide index
- _WARP_
-
warp index
- _INPSEQ_
-
input sequence values
- _TARSEQ_
-
target sequence values
- _INPPTH_
-
input path index
- _TARPTH_
-
target path index
- _METRIC_
-
distance metric values
The Warp Index indicates the total amount of warping for each slide. A negative number represents compression of the target sequence. A positive number represents expansion of the target sequence. The Warp Index is always zero for SLIDE=NONE and SLIDE=SEASON.
The sorting of the OUTPATH= data set depends on the SORTNAMES and the ORDER= option.
The OUTPATH= data set is ordered by the variables _INPUT_, then _TARGET_, then _TIMEID_ when ORDER=INPUTTARGET or ORDER=INPUT. The OUTPATH= data set is ordered by the variables _TARGET_, then _INPUT_, then _TIMEID_ when ORDER=TARGETINPUT or ORDER=TARGET.
If there are a large number of slides or warps or both, this data set might be large.
