Description
BCFDISPLAY
displays information about a random classification forest, constructed by the BCFOREST
procedure. 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
.
