Candidate values

Source: R/group_lasso.R
set_candidates.Rd

Sets candidate values for hyperparameters.

Usage

.set_candidates(tune)

Arguments

tune

character string for determining the candidate values for the hyperparameters:

  • "none": fixed weights and exponents (wgt_local=1, exp_local=1, wgt_global=0), no tuning

  • "weight": fixed exponents (exp_local=0, exp_global=1), tuning wgt_local=1-wgt_global

  • "exponent": fixed weights (wgt_local=1, wgt_global=0), tuning exp_local

  • "bivariate": tuning wgt_local=1-wgt_global and exp_local=exp_global

  • "factorial": tuning wgt_local, exp_local, wgt_global, exp_global

(to implement: data frame with columns wgt_local, exp_local, wgt_global, and exp_global)

Value

Returns a data frame with the slots "wgt_local" and "exp_local" for the local prior information and the slots "wgt_global" and "exp_global" for the global prior information.
