Factor Scaling in Lavaan for JASP
The JASP interface for Lavaan brings a lot of backend controls to the fron when computing SEM. But I'm running a model and found a strange button "Factor Scaling". I can't find any equivilent contrl in Lavaan's own documentation. It lets you choose between "Factor Loadings" (default in JASP), "Residual Variance", and "None". Switching between Factor Loadings and Residual Variance has a big effect on my coefficients and p-values, so I'm really curious to know that these options are used for. I've tried the same model out in RStudio and it looks like factor scaling is the same as the default I get running the model in RStudio. I've tried switching std.lv = TRUE, but I don't get the same results as "Residual Variance", so it's not just allowing the factors to float. Anyone know what this button is doing?
