LTFGRS: Implementation of Several Phenotype-Based Family Genetic Risk Scores

Implementation of several phenotype-based family genetic risk scores with unified input data and data preparation functions to help facilitate the required data preparation and management. The implemented family genetic risk scores are the extended liability threshold model conditional on family history (LT-FH++) from Pedersen (2022) <doi:10.1016/j.ajhg.2022.01.009> and Pedersen (2023) <https://www.nature.com/articles/s41467-023-41210-z>, Pearson-Aitken Family Genetic Risk Scores (PA-FGRS) from Krebs (2024) <doi:10.1016/j.ajhg.2024.09.009>, and family genetic risk score by Kendler (2021) <doi:10.1001/jamapsychiatry.2021.0336>.
