How to get "R-squared (R^2)" for endogenous latent variables with JASP SEM (Lavaan)?
I have spent so much time looking for the answer to this question but I've not made it so far.
Lavaan uses [ inspect(fit, 'r2') ] for R-squared but a table for "estimates" in JASP does not show R-squared.
Does my syntax in a model have a problem or is it JASP that does not provide an output for R-squared?
Then, how can I calculate R-squared for endogenous latent variables using factor loadings (estimates) and path coefficients?
