Arguments

data

a sgldata object

parameterGrouping

grouping of parameters, a vector of length p. Each element of the vector specifying the group of the parameters in the corresponding column of β.

groupWeights

the group weights, a vector of length length(unique(parameterGrouping)) (the number of groups).

parameterWeights

a matrix of size q \times p, that is the same dimension as β.

parameterNames

dim-names of parameters, if NULL dimnames(parameterWeights) will be used.

alpha

the α value 0 for group lasso, 1 for lasso, between 0 and 1 gives a sparse group lasso penalty.

test_data
