| Package: | huge |
| Type: | Package |
| Version: | 1.2.7 |
| Date: | 2015-09-14 |
| License: | GPL-2 |
| LazyLoad: | yes |
The package "huge" provides 8 main functions:
(1) the data generator creates random samples from multivariate normal distributions with different graph structures. Please refer to huge.generator.
(2) the nonparanormal (npn) transformation helps relax the normality assumption. Please refer to huge.npn.
(3) The correlation thresholding graph estimation. Please refer to huge.
(4) The Meinshausen-Buhlmann graph estimation. Please refer to huge.
(5) The graphical Lasso algorithm using lossless screening rule. Please refer and huge.
**Both (4) and (5) can be further accelerated by the lossy screening rule preselecting the neighborhood of each node via thresholding sample correlation.
(6) The model selection using the stability approach to regularization selection. Please refer to huge.select.
(7) The model selection using the rotation information criterion. Please refer to huge.select.
(8) The model selection using the extended Bayesian information criterion. Please refer to huge.select.
