I have a data set that looks like the following:
State Price
1. AL 40
2. AL 50
3. AL 40
4. AZ 20
5. AZ 20
6. AZ 30
7. AZ 40
8. CA 20
9. CA 50
10. CA 20
11. CA 40
12. CA 50
I would like to get a table with averages (on the
diagonal), and p-value for the test that two averages
are equal (off-diagonal):
AL AZ CA
AL avg(AL) p(AL=AZ) p(AL=CA)
AZ --- avg(AZ) p(AZ=CA)
CA avg(CA)
Since I have 50 states and I have to repeat the same
analysis for different variables and different data
sets, I was wondering whether there is an easy way for
doing this.
Thank you,
Raffaella Baldi
