Internal: Calculate difference between S and Sigma_hat
Calculate the difference between the empirical (S) and the model-implied indicator variance-covariance matrix (Sigma_hat) using different distance measures.
calculateDG( .object = NULL, .matrix1 = NULL, .matrix2 = NULL, .saturated = args_default()$.saturated, ... )
calculateDL( .object = NULL, .matrix1 = NULL, .matrix2 = NULL, .saturated = args_default()$.saturated, ... )
calculateDML(.object = NULL, .saturated = args_default()$.saturated, ...)
The functions are only applicable to objects inheriting class
cSEMResults_2ndorder. For objects of class
The geodesic and the squared Euclidian distance may also be
computed for any two matrices A and B by supplying A and B directly via the
.matrix2 arguments. If A and B are supplied
.object is ignored.
A single numeric value giving the distance between two matrices.
calculateDG: The geodesic distance (dG).
calculateDL: The squared Euclidian distance
calculateDML: The distance measure used by FIML
