Hi,
Is there anyone have some experience in the boost package. I used the
logitboost function to do the two-class classification.
This is the format I used.
logitboost(xtrain, ytrain, xtest, presel = 2, mfinal = 100) # with feature
selection
logitboost(xtrain, ytrain, xtest, presel = 0, mfinal = 100) # without feature
selection
xtrain is n*p, n is sample size, p is dimension
The error is always like this
Error in model.frame.default(formula = y ~ bx, weights = w/mean(w), na.action =
function (x) : invalid type (list) for variable 'bx'
I tried to implement by copying the original code of this function to track
down but still I don't know what's the reason.
Could somebody help me with that?
I greatly appreciate your help!
sincerely,
Linda
