Get standardized estimates with Monte Carlo bootstrapped standard errors
# S3 method for modsem_da
standardized_estimates(

An object of class modsem_da
Should standard errors be calculated using Monte Carlo simulation.
if FALSE
the delta method is used instead. Default is FALSE
.
Number of Monte Carlo repetitions
Tolerance for zero values. Standard errors smaller than this value will be set to NA.

The interaction term is not standardized such that var(xz) = 1
.
The interaction term is not an actual variable in the model, meaning that it does not
have a variance. It must therefore be calculated from the other parameters in the model.
Assuming normality and zero-means, the variance is calculated as
var(xz) = var(x) * var(z) + cov(x, z)^2
. Thus setting the variance of the interaction
term to 1 would only be 'correct' if the correlation between x
and z
is zero.
This means that the standardized estimates for the interaction term will
be different from those using lavaan
, since there the interaction term is an
actual latent variable in the model, with a standardized variance of 1.
