Fits panel data sg-LASSO regression model.
The function fits sg-LASSO regression based on chosen tuning parameter selection method_choice. Options include cross-validation and information criteria.
reg.panel.sgl(x, y, gamma = NULL, gindex, intercept = TRUE, method_choice = c("ic","cv"), nfolds = 10, method = c("pooled", "fe"), nf = NULL, verbose = FALSE, ...)
x |
NT by p data matrix, where NT and p respectively denote the sample size of pooled data and the number of regressors. |
y |
NT by 1 response variable. |
gamma |
sg-LASSO mixing parameter. γ = 1 gives LASSO solution and γ = 0 gives group LASSO solution. |
gindex |
p by 1 vector indicating group membership of each covariate. |
intercept |
whether intercept be fitted ( |
method_choice |
choose between |
nfolds |
number of folds of the cv loop. Default set to |
method |
choose between 'pooled' and 'fe'; 'pooled' forces the intercept to be fitted in sglfit, 'fe' computes the fixed effects. User must input the number of fixed effects |
nf |
number of fixed effects. Used only if |
verbose |
flag to print information. |

Other arguments that can be passed to |
