HMA: High-Dimensional Mediation Analysis

#' Example datasets for HIMA demo
#'
#' A \code{list} dataset containing datasets for various scenarios of HIMA. Each dataset contains a phenotype 
#' data frame and a high-dimension mediator data matrix. The datasets are simulated using parameters generated 
#' from real datasets. The code used to generate the data can be found in /inst/script folder of the package.
#' 
#' Example dataset 1 for HIMA: Continuous outcome 
#'
#' \itemize{
#'   \item Treatment: treated (value = 1) or not treated (value = 0)
#'   \item Outcome: outcome of the treatment- a normally distributed continuous variable
#'   \item Sex: female (value = 1) or male (value = 0)
#'   \item Age: Age of the participant
#' }
#'
#' Example dataset 2 for HIMA: Binary outcome 
#' 
#' \itemize{
#'   \item Treatment: treated (value = 1) or not treated (value = 0)
#'   \item Disease: diseased (value = 1) or healthy (value = 0)
#'   \item Sex: female (value = 1) or male (value = 0)
#'   \item Age: Age of the participant
#' }
#' 
#' Example dataset 3 for HIMA: Survival data outcome
#'
#' \itemize{
#'   \item Treatment: treated (value = 1) or not treated (value = 0)
#'   \item Status: Status indicator: dead (value = 1) or alive (value = 0)
#'   \item Time: time to event
#'   \item Sex: female (value = 1) or male (value = 0)
#'   \item Age: Age of the participant
#' }
#' 
#' Example dataset 4 for HIMA: Compositional mediator (e.g., microbiome)
#'
#' \itemize{
#'   \item Treatment: treated (value = 1) or not treated (value = 0)
#'   \item Outcome: outcome of the treatment- a normally distributed continuous variable
#'   \item Sex: female (value = 1) or male (value = 0)
#'   \item Age: Age of the participant
#' }
#' 
#' Example dataset 5 for HIMA: High-dimensional quantile mediation analysis
#'
#' \itemize{
#'   \item Treatment: treated (value = 1) or not treated (value = 0)
#'   \item Outcome: outcome of the treatment- abnormally distributed continuous variable
#'   \item Sex: female (value = 1) or male (value = 0)
#'   \item Age: Age of the participant
#' }
#'
#' @return A list of example datasets for HIMA demo and testing.
