Nettet24. jul. 2024 · The point of ridge regression is that you reduce the variance in your estimate at the cost of increasing bias (not reducing it as you say you would like). The reason effect sizes in the literature are inflated is because of publication bias (and small sample sizes which produce more variance in effect sizes). elektrodistribucija zrenjanin iskljucenjaNettet11. apr. 2024 · Fits linear ridge regression models for genome-wide SNP data.
