Correlated Columns in data frame
....Nataraj
Following is my previous message to this list to which I do
not get any reply.
Dear all,
For removing correlated columns in a data frame,df.
I found a code written in R in the page
http://cheminfo.informatics.indiana.edu/~rguha/code/R/ of
Mr.Rajarshi Guha.
The code is
#################
r2test <- function(df, cutoff=0.8) {
if (cutoff > 1 || cutoff <= 0) {
stop(" 0 <= cutoff < 1")
}
if (!is.matrix(d) && !is.data.frame(d)) {
stop("Must supply a data.frame or matrix")
}
r2cut = sqrt(cutoff);
cormat <- cor(d);

which alternative tests instead of AIC/BIC for choosing models
Dear R Users,
I am looking for an alternative to AIC or BIC to choose model parameters.
This is somewhat of a general statistics question, but I ask it in this
forum as I am looking for a R solution.
Suppose I have one dependent variable, y, and two independent variables,
x1 an x2.
I can perform three regressions:
reg1: y~x1
reg2: y~x2
reg3: y~x1+x2
The AIC of reg1 is 2000, reg2 is
