I wouldn't do it that way if I had a choice, just something if you're in a bind and want an approximation to start with until I got my hands on the real data.
Single-period you could do in excel and I suppose you could do more than one period if you wrote a VBA script.
R or Matlab is another alternative (R is free). |
