GraBLD: Gradient Boosted and LD adjusted

#' A genotype matrix.
#'
#' A dataset containing the genotypes of 927 SNPs on 5,000 individuals.
#'
#' @format A data matrix with 5000 rows and 927 columns:
#' \describe{
#' %\item{FID}{Family ID}
#' %\item{IID}{Within-family ID}
#' %\item{PAT}{Paternal within-family ID}
#' %\item{MAT}{Maternal within-family ID}
#' %\item{SEX}{Sex (1 = male, 2 = female, 0 = unknown)}
#' %\item{PHENOTYPE}{Main phenotype value}
#' %\item{SNP1}{Genotype of the first SNP}
#' %  ...
#' The genotype data matrix was generated by PLINK from .bed,
#' .bim and .fam files based on appropriate reference alleles. In
#' the analyses, the applied reference alleles among training data,
#' testing data and consortium data should be identical. The individuals in
#' the phenotype data were match with .fam file (i.e. the number of
#' individuals and the order of individuals should be same); The number
#' of SNPs in prediction variable matrix \code{annotations} is matched with that
#' in .bim data;
