Can't open miest.ster

[Sigrid Vikjord]

Dear Statalist,

I am trying do run a Cox regression on an imputed dataset using restricted cubic splines. I used the following code (the data are correctly stset, and stcox using the imputed datasets works fine):

mi set mlong                                                                                                                                     
mi register imputed HADSA_gli PartAg_gli Sex                                                                                                                  
mi impute chained (pmm, knn(10)) HADSA_gli PartAg_gli Sex , add(10)  

mi estimate, post  sav(miest, replace) : stcox i.HADS_A_gli PartAggli_spline1 PartAggli_spline2 i.Sex if glicopd_HUNT==1 | glicopd_HUNT==2 & HADS_A_gli!=. & PartAg_gli>=40.0 & PartAg_gli<=85.0

When I run the last command, I get the error message

r(603); file miest.ster could not be opened

, meaning that miest.ster exists, but can't be opened.

What do I do wrong?

I wonder whether the working directory was specified previously.

Hi,

I tried the following:

pwd

C:\Program Files (x86)\Stata15\docs


cd C:\Program Files (x86)\Stata15\docs

But still got the same error message r(603) when re-running mi estimate.

The next logical question might be: do you have write privileges to that directory? If it's a university computer, then you may not have write privileges. You could change the working directory to My Documents, where you probably have write privileges.

That worked, thank you

You are welcome. I am glad that this issue was easily resolved!
