I want to make comparison between company-year average of 2007-2010 and 2011-2013. desired outcome will look like: coname         year           ROA             ROA_pre         ROA_post company A    2007            20                 14                   0 company A     2008           10                 14                   0 company A     2009           17                 14                   0 compnay A     2010           9                   14                   0 company A     2011           1                   0                      3 company A     2012           -2                 0                      3 company A     2013           10                0                      3 company B     2007           2 company B     2008           8   Will proc summary be the answer?   Please help me.
