GRAB.getGenoInfo

This function shares input as in function <code>GRAB.ReadGeno</code>, please check <code>?GRAB.ReadGeno</code> for more details.

Provides a comprehensive suite of genome-wide association study (GWAS) methods
specifically designed for biobank-scale data. The package offers computationally efficient
and robust association tests for time-to-event traits (e.g., Bi et al., 2020
<doi:10.1016/j.ajhg.2020.06.003>), ordinal categorical traits (e.g., Bi et al., 2021
<doi:10.1016/j.ajhg.2021.03.019>), and longitudinal traits (Xu et al., 2025
<doi:10.1038/s41467-025-56669-1>). Additionally, it includes functions for
simulating genotype and phenotype data to support research and method development.
