Hi When i try to perform causal mediation analysis on my data. It gives a warning that co variance matrix for outcome is not positive definite. My variables are continuous. Also the results table does not give stnd. Errors.
A possible reason for non-positive definiteness is that there are linear dependency in the design matrix (if there are a lot of covariates). The standard errors are not produced due to the non-positive definiteness. Since more information may be needed to determine, this type of question may be best addressed with our technical support department.

Hi，
When I tried to run the "proc causalmed" procedure in my SAS 9.4 version, it showed that "proc causalmed not found". What can I do?
Hi Han! Thanks for your inquiry! We're checking on this for you!
