         Dear David, Dear R Users,    

   Calculation of Cross-Validation for SVM, with thoese time series which include negative and positive values ( for example return of a stock exchange index) must be different from a calculation of Cross-Validation with time series which includes just absolute values( for example a stock exchange index).   How is it calculated for a return time series?   Thank you very much for any help.
