We're trying to run this model with a categorical mediator and getting the following error message. We were not able to find anything useful in looking at Tech4 output. Any insights are appreciated! ________________________ categorical = sspacat26n; MODEL: wtkg56n on wtkg0n randn sspacat26n; sspacat26n on randn sspacat0n; randn with sspacat0n wtkg0n; wtkg0n with sspacat0n; model indirect: wtkg56n ind randn; WARNING: THE LATENT VARIABLE COVARIANCE MATRIX (PSI) IS NOT POSITIVE DEFINITE. THIS COULD INDICATE A NEGATIVE VARIANCE/RESIDUAL VARIANCE FOR A LATENT VARIABLE, A CORRELATION GREATER OR EQUAL TO ONE BETWEEN TWO LATENT VARIABLES, OR A LINEAR DEPENDENCY AMONG MORE THAN TWO LATENT VARIABLES. CHECK THE TECH4 OUTPUT FOR MORE INFORMATION. PROBLEM INVOLVING VARIABLE WTKG56N. |

You need to look at the TECH4 output or send the output with TECH4 and your license number to support@statmodel.com. |
