mutheta: Model-Implied Mean Vector

In jeksterslabds/jeksterslabRmedsimple: Jekster's Lab Simple Mediation Model Utilities

Description

Model-Implied Mean Vector from the simple mediation model.

Usage

mutheta(mux, deltam, deltay, taudot, beta, alpha)

Arguments

mux	Numeric. Mean of x ≤ft( μ_x \right) .
deltam	Numeric. Intercept of m ≤ft( δ_m \right) .
deltay	Numeric. Intercept of y ≤ft( δ_y \right) .
taudot	Numeric. Slope of path from x to y ≤ft( \dot{τ} \right).
beta	Numeric. Slope of path from m to y ≤ft( β \right) .
alpha	Numeric. Slope of path from x to m ≤ft( α \right) .

Details

The simple mediation model is given by

y_i = δ_y + \dot{τ} x_i + β m_i + \varepsilon_{y_{i}}

m_i = δ_m + α x_i + \varepsilon_{m_{i}}

The parameters for the mean structure are

\boldsymbol{θ}_{\text{mean structure}} = ≤ft\{ μ_x, δ_m, δ_y \right\} .

The parameters for the covariance structure are

\boldsymbol{θ}_{\text{covariance structure}} = ≤ft\{ \dot{τ}, β, α, σ_{x}^{2}, σ_{\varepsilon_{m}}^{2}, σ_{\varepsilon_{y}}^{2} \right\} .
