data |
list containing |
index |
vector indicating the group membership of each column of the covariate vector |
weights |
vector of observation weights |
maxit |
maximum iterations to run blockwise coordinate descent |
thresh |
iterate blockwise coordinate descent until the norm of the coefficient vector changes by less than this threshold |
min.frac |
ratio between the smallest and largest lambdas (lasso tuning parameters) |
nlam |
number of different lambdas (lasso tuning parameters) at which to fit the coefficients |
delta |
exponent of the unpenalized group coefficient norm in the adaptive penalty weight |
verbose |
print detailed information about model fitting? |
reset |
|
lambda |
vector of prespecified lasso tuning parameters - leave NULL to have the lambdas calculated automatically. |
unpenalized |
index of any unpenalized groups |
gamma |
a list containing the coefficients, tuning parameters, AIC/AICc/BIC/GCV values, degrees of freedom, fitted values, and residuals
