Sorry, I was thinking the sort order mattered when I first
replied. I agree with Maarten that -anova- makes more sense.

Hi,

I want to check if decile groups have significantly different values for
property B if you sort them by property A.
Example:
A group of 100 people, sort according to height, create 10 groups according
to deciles. For each resulting group 1 to 10 then calculate the average
weight. The null hypothesis I would like to check would be
weight1=weight2=....=weight10

Any suggestions on the test statistic and how to implement in Stata?

Thanks a lot, Tom
