I have a dataset of 1 records which I want to use to compare two
prediction models.
I split the records into test dataset (size = ntest) and training dataset
(size = ntrain). Then I run the two models.
Now I want to shuffle the data and rerun the models. I want many shuffles.
I know that the
Hi, Anybody used treenet here? I downloaded a demo but don't know how to
start with. Does R has something like treenet? Thanks,

Seems there is an exact non-parametric Bayes test for mean of non-negative
numbers as said on

I will check if R may have such package.

Hello, Gurus:
I tried to test if the sample mean of a dataset is zero.
The data has 1500 numbers with a lot of zeros and some small
positive numbers. The data range on [0,1] but the distribution is unknown.
It is zero inflated anyway.
I tried to use the Wilcoxon Signed Ranks test. But I read fr

Hello!
I am trying to use lm to do a simple regression but on a batch of
different files.
Each file has different column names.
I know the first column is the dependent variable and all the rest are
explanatory variables.
The column names are in the first line of the file.
But it seems lm() re

Thanks a lot for help. I have a question and I could not find clear answers

When we do logistic regression for one type of events of interest as a
proportion of a broader types of events, does the logistic regression assume
that the number of whole types of events should be ind
