I have written a routine to examine nonresponse bias based on a second,
unbiased "double sample." My output currently looks like this, an admix
of two "summ" commands and a bunch of numbers that the program calculates:
-> state = PA
sex
Sample 1:
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
sex | 24824 1.038471 .1923339 1 2
Sample 2:
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
sex | 580 1.077586 .2677502 1 2
Double sample mean for variable sex is 1.0623649
Associated standard error is .00680798
Estimated bias of single sample estimator is -.02389403
Estimated standard error is .00122073
Estimated RMSE is .02392519
Relative efficiency of double sample estimator (ratio to one sample RMSE):
0.28
Corresponding sample size for same MSE with one sample, 100% response:
1255
What I would prefer to do is synthesize this information in a
"nice" table of my own construction (since I have many variables). I seem
to remember somewhere about how to get command of output editing; but
other than a program for making tables of regression coefficients, I have
been unable to find any other instructions or examples....
Thanks in advance,
