The establishment of LASSO regression model. (Left) Curve of binomial deviation of MR-derived radiomic model varying with parameter λ. The vertical axis is binomial deviation. The horizontal axis represents the log (λ) value. The number above represents the number of selected features, and the λ at the minimum binomial deviation of the model is the optimal value (the curve of the image group characteristic coefficient of the vertical dotted line). (Middle) MR model changing with λ. The number above indicates the number of features filtered out. (Right) Imaging features screened by MR model.
