The parameter estimates that are most consistent with the data require negative variances, which cannot exist. 15 strong, > 0. If TRUE, the means of the observed variables enter the model.If "default", the value is set based on the user-specified model, and/or the values of other arguments.. int.ov.free:. If some variables are declared as ordered factors, lavaan will treat them as ordinal variables. Joreskog and Sorbom (1984) suggest that the problem may indicate that either that your model is wrong or that the sample is too small. The information matrix could not be inverted.

Though they have several potential causes, structural misspecification is among the most important. lavaan WARNING: some estimated ov variances are negative Object of class 'tidy_layout' Details. Warning message: In lav_object_post_check(object) : lavaan WARNING: some estimated ov variances are negative This is due to the fact that one of the residual variances .gpa4 is negative (i.e., $\hat{\theta}^{\delta}_{44}=-0.001$); a condition known as a Heywood case. Rather than estimate the factor loadings, here we only estimate the observed means and variances (removing all the covariances). warning(" lavaan WARNING: some estimated lv variances are negative ")} # 2. is cov.lv (PSI) positive definite? ).
