estat grangerplot not valid

[Cristina Jude]

Hello,

I am using Stata 17 on Windows 10 and I have a problem with the

estat grangerplot

command following didregress.
I get an error code r(321) estat grangerplot not valid.
I happens regardless of me using my own dataset or using the Stata manual example for didreress, which I find truly problematic.

 use "C:\Users\Matricule\Desktop\Folder\hospdd.dta"

 didregress (satis) (procedure), group(hospital) time(month)

Number of groups and treatment time

Time variable: month
Control:       procedure = 0
Treatment:     procedure = 1

. estat grangerplot
estat grangerplot not valid
r(321);

Do you have any idea how to fix this? Is this an incompatibility issue, a bug ..?

I am thinking about a potential system security problem/firewall as I also cannot directly open Stata manual datasets with the use command but have to download the .dta files separately and then open them in Stata.

. use https://www.stata-press.com/data/r17/hospdd
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
r(5100);

Thank you for your assistance.

Hi Cristina,

Please try typing:

update all, force

There might be an issue with your update. If this does not work, please let us know at [email protected].

Thank you for your reply. After forcing the update, the estat grangerplot works now. But not the direct opening of datasets.
I have adressed an inquiry to the Stata technical support.
