I downloaded the source tar file from Download | Dynare under the source tab.
I reran the tests and copied the tests/particle/first_spec_common.inc from the dynare repository tests/particle/first_spec_common.inc · master · Dynare / dynare · GitLab. The first two tests did not fail after that. I also copied matlab/missing/stats/gamrnd.m · master · Dynare / dynare · GitLab file over and the gamma distribution tests also did not fail.
However I still have 4 failing tests:
| * …/matlab/modules/dseries/src/@dseries/mean.m#3
| * …/matlab/modules/dseries/src/@dseries/mean.m#4
| * …/matlab/modules/dseries/src/@dseries/std.m#3
| * …/matlab/modules/dseries/src/@dseries/std.m#4
These tests seem to be commented out n the files that come packaged with the source tar. Do we know if that is why they are failing?
