You have difficulty using that option because it does not exists! xtreg
does
not have a noconstant option.
Why not running ols with the group and period dummies?
Anyway is a matter of interpretation, both regressions will give you the
same results.

Subject: st: noconstant (fixed effects models) (fwd)
Dear statalisters,
I have a question about fixed effects models using the xtreg
command. One, I am having difficulty getting the regression done with
the noconstant option.
I want to obtain the values of the parameters group 1, group 2 and
group 3(individuals effects) using the command xtreg without the
constant term of the equation
I have had no success when using the equations bellow without a
constant and no had success
When I make this regression, the program STATA 7.0 removes from the
results one of the parameter of the groups. I would like that it left
the results the parameter period 1 or period 9, and no one of the
parameters of the groups. I want to have control on that result. How to
do it?
xtreg lw group1 group2 group3 period8 exp exp2 ocupation childrens
regions if men==1, fe i(period) noconstant
or use
xtreg lw period1 period2 period3 period4 period5 period6 period7
period8 periood9 exp exp2 ocupation childrens regions if men==1, fe
i(group) noconstant
groups are individuals effects (represents the intercepts)
group1=22 at 32 ages of years
group2=33 at 43 ages of years
group3=44 at 54 ages of years
period1 at period9 are specific effects of the time.
