Can anyone tell me how to code permute properly to test if one modeled
growth rate (mod1) is greater than another (mod2).
Variations on the code below give me a perfect p-value each time. It
seems that I have to substitute something else for "mean" to come up
with the proper test statistic?
permute Mod1 mean=r(mean), reps(200) right nodots nodrop nowarn:
summarize Mod2
An example of the data is below.
Row Mod1 Mod2
1 1.113924 .7163003
2 1.122969 .7857646
3 1.057594 .7346777
4 1.153763 .8520272
5 1.148739 .8732744
6 .9890202 .7147149
