normalizing data sets
Hi,
Can someone tell me how to normalize a data set so that the mean of the set is 0 and the variance is 1. As I understand, when you
calculate the principle components of a data set through correlation as
< princomp( dataset, cor=T ) >
then a similar calculation is performed. I would like to know how I can perform such a calulation directly. Any help would be
greatly appreciated.
Many
