Reducing the dimensionality and granularity in hierarchical categorical variables

1 code implementation6 Mar 2024 Paul Wilsens, Katrien Antonio, Gerda Claeskens

We apply our methodology on a real dataset and find that the reduced hierarchy is an improvement over the original hierarchical structure and reduced structures proposed in the literature.

Selective inference using randomized group lasso estimators for general models

no code implementations24 Jun 2023 Yiling Huang, Sarah Pirenne, Snigdha Panigrahi, Gerda Claeskens

Selective inference methods are developed for group lasso estimators for use with a wide class of distributions and loss functions.

Nonparametric C- and D-vine based quantile regression

no code implementations9 Feb 2021 Marija Tepegjozova, Jing Zhou, Gerda Claeskens, Claudia Czado

Further, we show that the nonparametric conditional quantile estimator is consistent.

Detangling robustness in high dimensions: composite versus model-averaged estimation

no code implementations12 Jun 2020 Jing Zhou, Gerda Claeskens, Jelena Bradic

We find, however, that model-averaged and composite quantile estimators often outperform least-squares methods, even in the case of Gaussian model noise.

Fixed effects testing in high-dimensional linear mixed models

no code implementations14 Aug 2017 Jelena Bradic, Gerda Claeskens, Thomas Gueuning

A robust matching moment construction is used for creating a test that adapts to the size of the model sparsity.
