abess Python Package
Project description
abess: R & Python Softwares for Best-Subset Selection in Polynomial Time —
Best-subset selection aims to find a small subset of predictors such that the resulting linear model is expected to have the most desirable prediction accuracy. This project implements a polynomial algorithm proposed by Zhu et al (2020) to solve the problem. More over, the softwares includes helpful features for high-dimensional data analysis:
Linear regression, classification, counting-response modeling, censored-response modeling, multi-response modeling (multi-tasks learning)
sure independence screening
nuisance penalized regression
## Installation
### R-package You can install the stable version of R-package from [CRAN](https://cran.r-project.org/web/packages/abess):
` r install.packages("abess") `
### Python-package Install the stable version of Python-package from [Pypi](https://pypi.org/project/abess/) with: `shell pip install abess `
