Hello

I have the dataset as below. It is just one long row variable. I want to reshape using reshape long bV, i(group) j(year).
bV_1998_g1..... 1998 is year and is until 2010 and g1-g17 is a group. But there is no year and group variable so,this is not set as a time series variable.
How can I reshape this? Thank you!
