MICE stata 15

[Ayesha Sajjad]

Dear all,

In stata 15 the simple mi impute chained command (example):

mi impute chained (regress) var1 var2 (logit) var3 (ologit) var4 , add(10)

gives the following error in all my datasets which ran perfectly fine in stata 14:

invalid freeparm argument;
only "on" or "off" is allowed
error occurred during imputation of var1 var2 var3 var4 on m = 1

Something goes wrong I use logit/ologit/mlogit to impute categorical variables.

Thank you in advance for your help.

As a possible workaround, and as a diagnostic, what happens when you run it with versioning set to Stata 14?

[Richard Williams]

Do you have a replicable example? As always, make sure your version of Stata is up to date in case this is a bug that has been fixed.

[Ayesha Sajjad]

Thank you for your comments. Ben: It worked perfectly fine in stata 14.2 (the last stata version, before the update); Richard: I have set stata to automatically update each time I open it; I am sorry, I do not have a replicable example.

Another user has reported receiving the same error message in different circumstances. I have reported it to Stata Technical Support pointing them to the two topics.

Ayesha Sajjad can you tell us if you had any progress on this problem? Did you perhaps report it to Stata Technical Support?

The error message "invalid freeparm argument" is returned when an update for Stata 15 was not properly completed. For example, this can happen due to firewall or antivirus restrictions, Internet connection issues, or others. We recommend forcing and update by typing:

update all, force

If the problem persists, please send a reproducible example to [email protected], along with any error messages that might be returned during the updating process.
