Analyzing the data
1. Simulate yield for each of the surveyed farms
2. Plot observed yields vs. simulated yields
3. Compute bias for each field: bi = Obsi/Simi
4. Compute mean, standard deviation for observed
and simulated yields. Also, compute bias of
mean yields
5. Compute probability of exceedence of yields for
observed yields AND for simulated yields
6. Plot probability of exceedence for observed
yields AND for simulated yields
7. Adjust simulated yields using the mean bias
(bias of means, from #4 above)
yadj-i = ysim-i * biasmean
8. Compute probability of exceedence for bias
adjusted yields, and plot it on same graph as
probability of exceedence of observed yields
