The -S test via regression quantile affine LASSO
Sylvain Sardy, Ivan Mizera, Xiaoyu Ma +1
A novel test in the linear (LAD) and quantile regressions is proposed, based on the scores provided by the dual variables (signs) arising in the calculation of the (so-cal…
Partial Functional Linear Quantile Regression for Neuroimaging Data Analysis
Dengdeng Yu, Linglong Kong, Ivan Mizera
We propose a prediction procedure for the functional linear quantile regression model by using partial quantile covariance techniques and develop a simple partial quantile regressi…
Quasi-concave density estimation
Roger Koenker, Ivan Mizera
Maximum likelihood estimation of a log-concave probability density is formulated as a convex optimization problem and shown to have an equivalent dual formulation as a constrained…
Quantile tomography: using quantiles with multivariate data
Linglong Kong, Ivan Mizera
The use of quantiles to obtain insights about multivariate data is addressed. It is argued that incisive insights can be obtained by considering directional quantiles, the quantile…
