#' ECLS-K (2011) Sample Dataset for Demonstration
#'
#' A sample dataset extracted from the public-use Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011)
#' collected by the National Center for Education Statistics (NCES). This dataset is NOT a posting of the original data, and
#' it has been processed and formatted for use in demonstration purposes within this package. For access to the original
#' data, please visit the NCES data products page at \url{https://nces.ed.gov/ecls/dataproducts.asp}.
#'
#' The ECLS-K:2011 offers a comprehensive and detailed set of information about children's early life experiences,
#' focusing on children's health, development, education, and experiences in the years leading up to kindergarten.
#'
#' The sample dataset included in this package is used for demonstrating the functionality of the package's functions and
#' it does not include survey weights. In real analysis, the complex survey weights provided by NCES should be utilized
#' appropriately, for instance, as done in R packages such as \code{lavaan.survey} or \code{EdSurvey} if not using SEM.
#'
#' Please note that this data must not be used to attempt to identify respondents. For detailed documentation and proper usage of
#' the ECLS-K:2011 data, please refer to the original source at the National Center for Education Statistics (NCES) website:
