lisrel object.
This function can be used to extract matrices from the output of readLisrel.
lisrelMatrix(object, matrix, group = 1, type = "est")lisrelMatrix(object, matrix, group = 1, type = "est")
object |
A |
matrix |
Specification of the matrix to be extracted. See details. |
group |
An integer specifying which group the matrix should be extracted from. |
type |
Specification of the type of matrix to be extracted. |
LisrelToR uses the following names for the model matrices:
Lambda-Y matrix.
Psi matrix.
Beta matrix.
Theta-Epsilon matrix.
Tau-Y matrix.
Alpha matrix.
Lambda-X matrix.
Phi matrix.
Gamma matrix.
Theta-Delta matrix.
Tau-X matrix.
Kappa
The observed covariance matrix, or a list of such matrices for each group.
The implied covariance matrix, or a list of such matrices for each group.
Furthermore, lisrelToR uses the following names for matrix types:
Parameter estimates
Standard errors
t-values
Parameter numbers
A matrix.
