Any suggestion or solution? However, the model does not fit with reporting 'lavaan WARNING: some estimated lv variances are negative'. Including latent measurement models • specr - GitHub Pages By default, lavaan will always fix the factor loading of the first indicator to 1. There are three ways to generate a layout: Specify the layout in the call to get_layout() by providing node names and the number of rows to create a layout matrix. This may be a symptom that the model is not identified. We know the values of x1 x 1 and x2 x 2 and the correlation between them. Can anyone help with negative variance resulting in just identified ... In this case the model implied variances for your three variables are: 0.38, 2.44, and 2.56. The negative variance message may indicate that some exogenous variables have an estimated covariance matrix that is not positive definite.
