how to combine imputed data-sets from mice for classfication
Dear R users
I want to combine multiply imputed data-sets generated from mice to do
classfication.
However, I have various questions regarding the use of mice library.
For example suppose I want to predict the class in this data.frame:
data(nhanes)
mydf=nhanes
mydf$class="pos"
mydf$class[sample(1:nrow(mydf), size=0.5*nrow(mydf))]="neg"
mydf$class=factor(mydf$class)
First I...

genetic algorithm
Hi,
I am doing some research on feature selection for classfication
problem using genetic algorithm in a wrapper approach. I am wondering
if there is some package which is already built for this purpose. I
was advised before about dprep package but I don't think it used GA
there (if I am wrong, please correct me!)
Thanks,
Ed

Random Forests theoretical question
I feel like a dope for asking this, but after reading various articles I'm
still not quite sure I get it. What is the relationship or similarity
between a "probability" prediction from a classfication random forest and a
Bayesian posterior probability? Can they be considered similar, or would I
need to take that probability and project it through a likelihood (I'm
thinking, perhaps wrongly, of computing this from the confusion matrix) to
get a posterior probability?
Something about that...
