lisrel_obs: LISREL Structural Equations with Observed Variables.

In jeksterslabds/jeksterslabRds: Jekster's Lab Data Science and Statistics

Description

Model-implied variance-covariance matrix (\boldsymbol{Σ} ≤ft( θ \right)) using the LISREL notation for structural equations with observed variables.

Usage

lisrel_obs(BE, I, GA, PH, PS)

Arguments

BE	\mathbf{B}_{m \times m} coefficient matrix for endogenous variables.
I	\mathbf{I}_{m \times m} identity matrix.
GA	\boldsymbol{Γ}_{m \times n} coefficient matrix for exogenous variables.
PH	\boldsymbol{Φ}_{n \times n} variance-covariance matrix of \boldsymbol{ξ}.
PS	\boldsymbol{Ψ}_{m \times m} variance-covariance of \boldsymbol{ζ}. \boldsymbol{ζ} is a matrix of residual variances and covariances in regression equations.

Details

Combines \boldsymbol{Σ}_{\mathbf{yy}} ≤ft( \boldsymbol{θ} \right) (lisrel_obs_yy), \boldsymbol{Σ}_{\mathbf{yx}} ≤ft( \boldsymbol{θ} \right) (lisrel_obs_yx), \boldsymbol{Σ}_{\mathbf{xy}} ≤ft( \boldsymbol{θ} \right) (lisrel_obs_xy), and \boldsymbol{Σ}_{\mathbf{xx}} ≤ft( \boldsymbol{θ} \right) (\boldsymbol{Φ}) to produce \boldsymbol{Σ} ≤ft( \boldsymbol{θ} \right).

Value

Returns the model-implied variance-covariance matrix (\boldsymbol{Σ} ≤ft( \boldsymbol{θ} \right)) derived from the \mathbf{B} (BE), \mathbf{I} (I), \boldsymbol{Γ} (GA), \boldsymbol{Φ} (PH), and \boldsymbol{Ψ} (PS) matrices.
