The third day of the Workshop on Statistical Machine Learning Methods for Genomic Prediction Using R Program was held on Thursday, June 19, 2025, at 10:00-13:00 WIB in the FMIPA UNY Ballroom. In this session, Professor Osval continued the material from the previous day by discussing the application of the ridge regression and lasso regression methods to several datasets, namely Trouser, Dog, and Toy EYT using the help of Rstudio software. In addition, he also explained the mixed models method for genomic prediction, Bayesian ridge regression, and Bayesian genomic linear regression, starting from the definition and basic concepts, the statistical models used, to how to apply them in the real world using RStudio software.
