In modsem: Latent Interaction (and Moderation) Analysis in Structural Equation Models (SEM)

Get data with product indicators for different approaches

Description

get_pi_syntax() is a function for creating the lavaan syntax used for estimating latent interaction models using one of the product indicators in lavaan.

Usage

get_pi_data(model.syntax, data, method = "dblcent", match = FALSE, ...)

Arguments

model.syntax	lavaan syntax
data	data to create product indicators from
method	method to use: "rca" = residual centering approach, "uca" = unconstrained approach, "dblcent" = double centering approach, "pind" = prod ind approach, with no constraints or centering, "custom" = use parameters specified in the function call
match	should the product indicators be created by using the match-strategy
...	arguments passed to other functions (e.g., modsem_pi)

Value

data.frame

Examples

library(modsem)
library(lavaan)
m1 <- '
  # Outer Model
  X =~ x1 + x2 +x3
  Y =~ y1 + y2 + y3
  Z =~ z1 + z2 + z3

  # Inner model
  Y ~ X + Z + X:Z
'
syntax <- get_pi_syntax(m1)
data <- get_pi_data(m1, oneInt)
est <- sem(syntax, data)
