Forward selectionThis paper suggests a method for bootstrapping the multiple linear regression model $$Y = \\beta _1 + \\beta _2 x_2 + \\cdots + \\beta _p x_p + e$$ Y = β 1 + β 2 x 2 + + β p x p + e after variable selection. We develop asymptotic theory for ...

(2016) considered variable selection for both functional and non-functional parts based on FPCA approach; Zhang et al. (2019) used wavelet-based sparse group lasso to select important functional predictors for partially functional linear quantile regression models with multiple functional covariates. ...

Multiple Linear Regression Multiple linear regression (MLR) is a method used to model the linear relationship between a dependent variable (target) and one or more independent variables (predictors). MLR is based on ordinary least squares (OLS), the model is fit such that the sum-of-squares ...
