He started the year recording a loss in all three of his starts, and his ERA sits over 6.00. However, advanced metrics indicate he may be the victim of some bad luck to start the year.

Least Angle Regression¶ Least-angle regression (LARS) is a regression algorithm for high-dimensional data, developed by Bradley Efron, Trevor Hastie, Iain Johnstone and Robert Tibshirani. LARS is similar to forward stepwise regression. At each step, it finds the predictor most correlated with the response. rajani pronounceNettetBoth the lasso and least angle regression can be applied with the R function. By default, the lasso method is used. To use least angle regression, set the argument type=“lar”.
