You should expect 9 regressions: you are modeling the first to the
ninth decile and never the zeroth or the tenth decile (being the
minimum and the maximum). This is implicit in the description of the
description of the -quantile()- option in the helpfile of -sqreg-: 
"quantile(#) specifies the quantile to be estimated and should be a
number between 0 and 1, exclusive."

Hope this helps,
