Hello,
does any one know how to interpret this output in R?

> Classification with logitboost
> fit <- logitboost(xlearn, ylearn, xtest, presel=50, mfinal=20)
> summarize(fit, ytest)
Minimal mcr:   0 achieved after 6 boosting step(s)
Fixed mcr:     0 achieved after 20 boosting step(s)

What is "mcr" mean?

Thanks
