| 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 expnasion 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.
