st: esttab error - too many base levels specified

[Deborah Goldschmidt <dgoldjunk@gmail.com>]

Hello,

I'm running a bunch of regressions, storing the results, and trying to 
output the results using esttab. Whenever I run my regressions and 
include state or year dummies, esttab gives me the error "too many base 
levels specified" (even though the dummies aren't included in the 
table).  If I run the regressions without the state & year dummies, 
there's no problem. Is there any way to fix this, so that I can include 
the dummies in my analysis and still get the table I want?

Thank you!

here is some of my code:
eststo clear
eststo y1Reg: reg y1 law i.state i.year, cluster(state)
eststo y2Reg: reg y2 law i.state i.year, cluster(state)
eststo y3Reg: reg y3 law i.state i.year, cluster(state)

esttab y* using myfile.tex, replace b(a2) se ///
            dropped(---) star(* 0.1 ** 0.05 *** 0.01) ///
            mlabels(, none) label nogaps nonotes noobs ///
            noconstant keep(law) ///
            nolines delimit(&) end(\\) posthead("\addlinespace") ///
            nonumbers  ///
            varwidth(46) modelwidth(21) ///
            noisily
