8.31 To apply BART:

• We must select the number of trees $K$, the number of iterations $B$ and the number of burn-in iterations $L$

• Typically, large values are chosen for $B$ and $K$ and a moderate value for $L$: e.g. $K$ = 200, $B$ = 1,000 and $L$ = 100

• BART has been shown to have impressive out-of-box performance - i.e., it performs well with minimal tuning
