Control function for xtune
fitting.
1 2 3 |
alpha.init |
initial values of alpha vector supplied to the algorithm. alpha values are the hyper-parameters for the double exponential prior of regression coefficients, and it controls the prior variance of regression coefficients. Default is a vector of 0 with length p. |
maxstep |
Maximum number of iterations. Default is 100. |
tolerance |
Convergence threshold. Default is 1e-4. |
maxstep_inner |
Maximum number of iterations for the inner loop of the majorization-minimization algorithm. |
tolerance_inner |
Convergence threshold for the inner loop of the majorization-minimization algorithm. |
compute.likelihood |
Should the function compute the marginal likelihood for hyper-parameters at each step of the update? Default is TRUE. |
verbosity |
Track algorithm update process? Default is FALSE. |
standardize |
Standardize X or not, same as the standardized option in glmnet |
intercept |
Should intercept(s) be fitted (default=TRUE) or set to zero (FALSE), same as the intercept option in glmnet |
