I am receiving an error message when trying to run a proc calis statement: The sample covariance or correlation matrix is not positive definite. I'm unsure how to corrrect the issue. Below is a screen shot of my code and error. If anyone has any suggestions, I'd be willing to try them! I'm wondering if the issue doesn't have to do with missing values in my variables. But I'm a novice, and haven't ran a proc calis before. Thanks in advance for any help!
