#' Dataset mmLSTrf_exampledata.
#'
#' A simulated dataset illustrating data for a study design with 2 fixed
#' situations, 3 measurement occasions, 2 methods and 3 indicators.
#'
#' The variables are named after the following format: \eqn{Y_{imts}}
#' (i = indicator, m = method, t = occasion, s = fixed situation)
#' \itemize{
#' \item \eqn{Y_{1111}}
#' \item \eqn{Y_{2111}}
#' \item \eqn{Y_{3111}}
#' \item \eqn{Y_{1211}}
#' \item \eqn{Y_{2211}}
#' \item ...
#' \item \eqn{Y_{2132}}
#' \item \eqn{Y_{3132}}
#' \item \eqn{Y_{1132}}
#' \item \eqn{Y_{2232}}
#' \item \eqn{Y_{3232}}
#' }
#'
#' This format reflects the order of indicator variables in a path diagram, where
#' indicators are first grouped by fixed situations, within those they are then
#' grouped by occasions and within those they are lastly grouped by methods.
#' The resulting nested structure has indicators nested within methods, nested
#' within occasions, nested within fixed situations.
#'
#' The specified population values underlying the simulated data are:
#' \itemize{
#' \item \eqn{E(T_{111})} = 2.90
#' \item \eqn{Comm(T_{112})} = 0.74
#' \item \eqn{E(T_{112})} = 3.50
#' \item \eqn{\epsilon_{imts}} = 0.15
#' \item \eqn{Var(T_{111})} = 0.40
#' \item \eqn{\alpha_{ims}} = 0.00
#' \item \eqn{Var(T_{112})} = 0.98
#' \item \eqn{\lambda_{ims}} = 1.00
#' \item \eqn{Var(O_{11t1})} = 0.20
#' \item \eqn{\delta_{ims}} = 1.00
#' \item \eqn{Var(O_{11t2})} = 0.35
#' \item \eqn{\gamma_{ims}} = 1.00
#' \item \eqn{Var(TM_{ims})} = 0.10
#' \item \eqn{\beta_{1112}} = 0.35
#' \item \eqn{Var(OM_{mts})} = 0.10
#' \item \eqn{\beta_{0112}} = -0.21
#' \item \eqn{Var(\omega_{11s})} = 0.20
#' }
#' Trait factors are essentially parallel, other latent variables are essentially
#' equivalent. Scalar MI holds across fixed situations and methods. Latent
#' variables are orthogonal apart from trait factors.

#' Data was assessed 5 times a day on 5 days during an experience-sampling study.
#' Additionally, this dataset contains measures of the Big Five personality dimensions from an intake session before the experience sampling phase.
#' The Big Five personality dimensions reflect mean values of 2 items each, one of which reverse coded (Gosling et al., 2003; Muck et al., 2007)
#' This dataset can be used to demonstrate how covariates (Big Five) contribute to trait components of Latent State-Trait models.
