This looks like a job for the -parmest- package, downloadable from SSC )if you have Stata 11 or 12) or from my websire (if you have any of Stata versions 5 to 10). The -parmest- package produces an output dataset (or resultsset) with 1 observation per parameter and data on the parameter estimates, confidence intervals, P-values, or other parameter attributes specified by the user. Multiple resultssets can be concatenated (using -append-), subsetted (using -keep-), sorted (by the P-values or otherwise), and output with whatever format the user wants to specify. And the on-line help for -parmest- contains a lot of hypertext references to Stata Journal articles and Stata User Meeting presentations on -parmest-.

I hope this helps.

Best wishes

Roger

Hello,

    I am trying to write a code which will go through around 500 ordinal logistic regressions and the output is the id for each of the rs # and the corresponding p-values, where the p-values are sorted in ascending order. i want the p-values reported up to 10 decimal places. This is my code so far. I may be wrong here. How do I make Stata report p-values up to 10 decimal places? Do I need to specify e(b) under display if I want the beta coefficients printed out for each rs #?


~~~~~~~~
local list "age sex c1 c2 c3"
local pvalue = e(p)

foreach `x’ of varlist rs1-rs500 {

quietly ologit outcome `x' `list'

sort pvalue
display `x' pvalue
}

~~~~~~~~

I am using Stata 11.1.

I want the output to show the following:

~~~~

rs5       5e-7
rs493   4e-6
...
...
rs257   0.33

~~~

Thanks,

   Debs
