Re: st: Decile regression using sqreg

I'm having a problem using the "sreg" command in Stata. I'd like to
run a regression foreach DECIL of the income distribution of a
country, so I've told Stata to do this:
sqreg income expenditure, quantiles(.1 .2 .3 .4 .5 .6 .7 .8 .9 1)
You only need nine cutpoints to create ten deciles. The 1 at the end
is unnecessary.
But Stata is performing the regression for the nine first decils and
for the quantile 1 (I think, because in the output I have the
estimation results for the: q10 q20 ....q90 q1).
The words we use are confusing; 'decile' is used for both the
interval containing 10% of the data and for the upper cutpoint for
this interval.
