The predictLifetime function is used to compute lifetime PD. When making lifetime predictions: A different data set is likely used, not the data you used for training and validation, but a new data set with forward-looking projections for different loans. The projected values in the lifetime...

Lasso Regression: Lasso regression is another variation of linear regression that uses L1 regularization to prevent overfitting. The regularization term adds a penalty term to the cost function, which helps to keep the coefficients of the model small. This model was trained on the data and the re...
