Boost in R
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

dlda{supclust} 's output
Hi,
I am using dlda algorithm from supclust package and I am wondering if
the output can be a continuous probability instead of discrete class
label (zero or one) since it puts some restriction on convariance
matrix, compared with lda, while the latter can.
thanks,
