Code to implement simulations and data analyses from "A perturbation method for inference on regularized regression estimates"

The functions in this code can be used to obtain confidence intervals for regression coefficients from certain regularized regression methods. Please see the article for reference.

Minnier, J., Tian, L. & Cai, T. (2011), "A perturbation method for inference on regularized regression estimates"", Journal of the American Statistical Association 106(496), 1371–1382.

Instructions

Simulations

To replicate the simulations, run the files:

1-run-ResampleALASSO-simulations.R
2-run-CompressResample-simulations.R
3-run-Summary-simulations.R

for various values of paramnum to obtain different settings.

Data Analysis

To replicate the data analysis, run the file:

ALASSO-HIVexample-May2012.R

Functions

Functions required to implement our methods can be found in the files:

functions-regression.R
functions-CIs.R

The former provides functions to perform adaptive LASSO and perturbation of adaptive LASSO estimates. The latter provides functions to obtain various confidence intervals presented in the paper.
