distance_measures {cSEM} | R Documentation |
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 = FALSE, ... ) calculateDL( .object = NULL, .matrix1 = NULL, .matrix2 = NULL, .saturated = FALSE, ... ) calculateDML( .object = NULL, .matrix1 = NULL, .matrix2 = NULL, .saturated = FALSE, ... )

An R object of class cSEMResults resulting from a call to |

Logical. Should a saturated structural model be used?

The distances may also be computed for any two matrices A and B by supplying
A and B directly via the .matrix1
and .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

: The distance measure (fit function) used by ML
