chi2datajufe
<br>
number of observations (_N) was 0, now 150
<br>
unknown function rchi()
<br>
r(133);<br>
这是上面的命令<br>
program chi2datajufe, rclass
<br>
  1. drop _all
<br>
  2. set obs 150
<br>
  3. generate x=rchi2(1)
<br>
  4. generate u=rchi(1)-1
<br>
  5. generate y=1+2*x+u
<br>
  6. regress y x
<br>
  7. return scalar b2=_b[x]
<br>
  8. return scalar se2=_se[x]
<br>
  9. return scalar t2=(_b[x]-2)/_se[x]
<br>
10. return scalar r2=abs(return(t2))>invttail(148, .025)
<br>
11. return scalar p2=2*ttail(148, abs(return(t2)))
<br>
12. end
<br>
