[R] Determining r2 values for a SEM
Hello, I have been using the SEM package and developed 4 models that all have an adequate fit. I require r2 values for the variables in my SEM and cannot find a way to get r2 values for a SEM. I have attempted using the smc (squared multiple correlation) function, but this only takes the initial covariance matrix and not the fitted SEM as arguements, so the r2 values cannot be correct. Is there a way to determine r2 values for an SEM in the SEM package or another way to get these values in R?

Katherine, rsquare.sem() in package sem.additions will do it for you.

Dear Mark and Katherine, As well, version 2.0-0 of the sem package on R-Forge, and soon to be on CRAN, includes R^2 values as part of the summary() output (along with many other enhancements).
