Unified Algorithm for Non-convex Penalized Estimation for
Generalized Linear Models
An efficient unified nonconvex penalized estimation algorithm for
Gaussian (linear), binomial Logit (logistic), Poisson, multinomial Logit,
and Cox proportional hazard regression models.
The unified algorithm is implemented based on the convex concave procedure and
the algorithm can be applied to most of the existing nonconvex penalties.
The algorithm also supports convex penalty:
least absolute shrinkage and selection operator (LASSO).
Supported nonconvex penalties include
smoothly clipped absolute deviation (SCAD),
minimax concave penalty (MCP), truncated LASSO penalty (TLP),
clipped LASSO (CLASSO), sparse ridge (SRIDGE),
modified bridge (MBRIDGE) and modified log (MLOG).
For high-dimensional data (data set with many variables),
the algorithm selects relevant variables producing a parsimonious regression model.

High-level R Interface to NetCDF Datasets
This package provides a high-level R interface to Unidata's NetCDF
data files. Using this package netCDF datasets, and all their
associated metadata, can be read and written in one go. It is also
easy to create datasets including lots of metadata.
This package supports both the CF and default NetCDF metadata conventions.
This package
supports more general NetCDF files and conventions than the ncdf
package by David Pierce. It uses the low-level NetCDF package
RNetCDF by Pavel Michna.
