Dear Martin,
�
It�works well.� I was able to calculate moving growth rate for many countries for�several years in a single click. I greatly appreciate your help. Thank you.

> Dear list members,

> I have time series data (2000-2007) on crop yield for three countries. I

> 2000-02, 2001-03,.....2005-07). My equation is log(yield) = a + b(time).
> The growth rate is (b*100). I would like to write a loop command or any
