Displays information about a random classification forest (R.W. Payne).
Option
PRINT = string tokens |
Controls printed output (outofbagerror, confusion, importance, orderedimportance, idoutofbag); default * i.e. none |
|---|
Parameter
SAVE = pointers |
Save structure from BCFOREST providing information about the random forest |
|---|
Description
BCFDISPLAY displays information about a random classification forest, constructed by the BCFOREST procedure. The SAVE parameter can be set to a pointer, saved using the SAVE option of BCFOREST, containing the necessary information about the forest. Alternatively, if you do not set SAVE, information will be printed about the forest most recently constructed by BCFOREST.
The output is controlled by the PRINT option, with settings:
outofbagerror |
out-of-bag error rate, |
|---|---|
confusion |
confusion matrix, |
idoutofbag |
out-of-bag identifications of the individuals, |
importance |
importance ratings of the X variates and factors, and |
orderedimportance |
importance ratings of the X variates and factors in decreasing order. |
The default is PRINT=* i.e. no printing
Option: PRINT.
Parameter: SAVE.
