Overfitting bias variance tradeoff

WebSample size strongly influences the bias–variance tradeoff (Hastie et al. 2009), wherein models with many parameters run the risk of overfitting the data (high bias, with poor out-of-sample accuracy), while models with few are more prone to underfit the data (high variance, with increased sensitivity of coefficients to small changes in data ...
