Demonstration

Mediation Analysis

With the mediation() function from the semUtils package, you can automatically estimates the indirect effects of a lavaan syntax.

library(semUtils)

database <- read.csv("SmartHomes.csv")

model <- '
  EE =~ EE1 + EE2 + EE3
  PE =~ PE1 + PE2 + PE3 + PE4
  PTS =~ PTS1 + PTS2 + PTS3
  PTF =~ PTF1 + PTF2 + PTF3
  PC =~ PC1 + PC2 + PC3 + PC4 + PC5 + PC6 + PC7 + PC8 + PC9
  T =~ T1 + T2 + T3 + T4
  SWB =~ SWB1 + SWB2 + SWB3
  BI =~ BI1 + BI2 + BI3

  PE ~ EE
  T ~ PC + PTS + PTF
  SWB ~ T + PE + EE
  BI ~ PE + SWB + T
'

mediation(model = model,
          database = database,
          confidence_interval = 95,
          bootstrap_samples = 1000)

Moderation Analysis

With the moderation() function from the semUtils package, you can easily estimates the interaction latent variables following Ping (1995).

database <- read.csv("SmartHomes.csv")

model <- '
  EE =~ EE1 + EE2 + EE3
  PE =~ PE1 + PE2 + PE3 + PE4
  PTS =~ PTS1 + PTS2 + PTS3
  PTF =~ PTF1 + PTF2 + PTF3
  PC =~ PC1 + PC2 + PC3 + PC4 + PC5 + PC6 + PC7 + PC8 + PC9
  T =~ T1 + T2 + T3 + T4
  SWB =~ SWB1 + SWB2 + SWB3
  BI =~ BI1 + BI2 + BI3
  UI =~ UI1 + UI2 + UI3

  PE ~ EE
  T ~ PC + PTS + PTF
  SWB ~ T + PE + EE + UI
  BI ~ PE + SWB + T
'

moderation(model = model,
          database = database,
          dependent_variable = "SWB",
          independent_variable = "PE",
          moderating_variable = "UI")
