BT_perf {BT}  R Documentation 
Performance assessment.
Description
Function to compute the performances of a fitted boosting tree.
Usage
BT_perf(
BTFit_object,
plot.it = TRUE,
oobag.curve = FALSE,
overlay = TRUE,
method,
main = ""
)
Arguments
BTFit_object 

plot.it 
a boolean indicating whether to plot the performance measure. Setting 
oobag.curve 
indicates whether to plot the outofbag performance measures in a second plot. Note that this option makes sense if the 
overlay 
if set to 
method 
indicates the method used to estimate the optimal number of boosting iterations. Setting 
main 
optional parameter that allows the user to define specific plot title. 
Value
Returns the estimated optimal number of iterations. The method of computation depends on the method
argument.
