Dear all, I need to compute the "average rate of growth of variable - y-, over the previous three years".
Could somebody help me with the command?

g growth = D.linvest
mvsumm growth, gen(grate) stat(mean) window(3) end
l year invest linvest D.linvest grate if company==1
tsline grate if company==1, yline(0)
