Hi,

I have the following problem. When using the fastxtile command to sort my values into deciles, one decile group is missing. After some testing I found that for a certain month in my observation period I get the following percentile breakpoints after using pctile with option nq(10).
pt_sent_10
-0.08
0
0
0.0377778
0.08
0.14
0.19
0.28
0.38
It seems like the breakpoints for the second and third class are the same. Does that mean that I don't have enough variation in my values?
Do I have to use less groups or is there another way?

Best regards
Nic
