RE: st: p value precision in clogit output
Need to convert date format of YYYYMMDD into Stata date format. Does anyone have a short do-file to accomplish this?
Thank you,
Dan

Hello Luisa,
run your model with clogit but without an "or" option.
You will get a coefficient and standard error output.
Get the precise Z-value
Use the following formula:
p=2*(1-norm(abs(c)/se))
where c is the coefficient and se -- its standard error.
E.g.:
sysuse auto
clogit foreign weight, group(gear_ratio) di 2*(1-norm(abs(-.0013891)/.0020871))
rounded value is 0.506
more precise value is .5056894
Use saved results to access the coefficients in your program if necessary. See -ereturn list-.
Best regards,
Sergiy Radyakin
