Function to implement the soft-, MCP, SCAD thresholding rule in the ADMM method.
1 | thresh_est(z, lambda, tau, a = 3, penalty = c("MCP", "SCAD", "lasso"))
|
z |
a vector where the function is to be evaluated. |
lambda |
a number representing a tuning parameter. |
tau |
the penalty parameter in the ADMM method. |
a |
the tuning parameter of the MCP/SCAD penalty (see details). Default is 3 for MCP and 3.7 for SCAD. |
penalty |
The penalty to be applied to the model. Either "lasso" (the default), "SCAD", or "MCP". |
A vector containing the threshlding values at z.
