Thanks Nick, yes exactly, my question is why the ladder function fails
to provide any chi-square values here. I'll attach the Stata output
here:
. ladder disp_2000
Transformation formula chi2(2) P(chi2)
------------------------------------------------------------------
cubic dis~2000^3 . .
square dis~2000^2 . .
identity dis~2000 . .
square root sqrt(dis~2000) . 0.000
log log(dis~2000) . 0.000
1/(square root) 1/sqrt(dis~2000) . 0.000
inverse 1/dis~2000 . 0.000
1/square 1/(dis~2000^2) . 0.000
1/cubic 1/(dis~2000^3) . 0.000
. sum disp_2000, detail
Number displaced 2000 (if data unavailable go up
to 2003
-------------------------------------------------------------
