r internal representation and what you get back at
the end of regression is essentially 1-based indexed like your input so 0.11
maps onto from F1and so on?

Did you check the indices in the LIBSVM data and the master file? Do
they match? -Xiangrui

Hi All,I use LIBSVM format to specify my input feature vector, which used
1-based index. When I run regression the o/p is 0-indexed based. I have a
master lookup file that maps back these indices to what they stand or. However,
I need to add offset of 2 and not 1 to the regression outcome during
