Hello, I am working with a path analyses (no latent variables) in MPlus. I want to extract the variances of the estimates of the path coeffcients and compute manually their Standard Errors and standard deviations. If Im not wrong, I can extract them form the variancecovariance matrix using TECH3 and then compute them using the formula SE= SD/sqrt(n) and SD = sqrt(variance), is that right? Thanks in advance 


The standard errors are printed in the regular output under the SE heading. You don't need to go via Tech3. What Tech3 adds is the covariance among parameter estimates.

Thanks so much And extra question not closely related with this one: is there any place (user guide, technical appendix or similar) where I can consult the equations and formulas used to compute the Likelihood and the AIC and BIC values? Thanks in advance
