Option
PRINT = string tokens |
Controls printed output (outofbagerror, youtofbagestimates, importance orderedimportance); default * i.e. none |

Parameter
SAVE = pointers |

Description
BRFDISPLAY displays information about a random regression forest, constructed by the BRFOREST procedure. The SAVE parameter can be set to a pointer, saved using the SAVE option of BRFOREST, 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 BRFOREST.
The output is controlled by the PRINT option, with settings:
outofbagerror |
out-of-bag error rate, |
|---|---|
youtofbagestimates |
out-of-bag predictions of the y-values, |
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
