Hi Nick,

What is the new command cusum for time series data then? The cusum commmand does not work saying data are out of range.

>>>>> Thanks Anders. I changed "gra" to "graph" and I got "gpopgraph_g.new petindex, s([year]) xlab ylab: class member function not found" message. To say it frankly, it's my first time using stata and I have stata12; therefore it's hard for me to know what has changed and from where. How about the other problems I long for answers?
