In JonasMoss/reliable: Reliability Coefficients and Factor Scores for the Linear Factor Model

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>",
  fig.path = "man/figures/README-"
)

reliable

An R package for reliability coefficients and factor scores for the linear factor model.

library("attenuation")
knitr::opts_chunk$set(echo = TRUE)
knitr::opts_chunk$set(out.width='750px', dpi=200)

Installation

From inside R, use the following command:

# install.packages("devtools")
devtools::install_github("JonasMoss/reliable")

Usage

Use lavaan to fit a linear factor model.

library("reliable")

model = ' visual  =~ x1 + x2 + x3
          textual =~ x4 + x5 + x6
          speed   =~ x7 + x8 + x9 '

object = lavaan::cfa(model = model,
                     data = lavaan::HolzingerSwineford1939)

Now you we can find the sum-score reliability and the associated factor scores.

reliability(object, type = "sumscore")

And we can find the linear reliability and the associated factor scores.

reliability(object, type = "linear")
