Fit Graphical Lasso with estimate regularization parameter from Robust Selection
1 | robsel.glasso(x, alpha = 0.9, B = 200, ...)
|
x |
A |
alpha |
Prespecified confidence level. Default 0.9 |
B |
Number of bootstrap sample. Default 200 |
... |
Optional arguments passed on to glasso. |
A list with components:
alpha |
A list of prespecified confidence level |
lambda |
A list of estimate regularization parameter for Graphical Lasso |
Omega |
A list of estimated inverse covariance matrix |
Sigma |
A list of estimated covariance matrix |
Each item in each component corresponds to a prespecified level alpha.
