Arbitrary Conditional Distributions with Energy

CoRR, 2021
Modeling distributions of covariates, or density estimation, is a core challenge in unsupervised learning. However, the majority of work only considers the joint distribution, which has limited utility in practical situations. A more general and useful problem is arbitrary conditional density estimation, which aims to model any possible conditional ...

Are there asymmetries in the effects of training on the conditional male wage distribution? [PDF]

, 2010
Recent studies have used quantile regression (QR) techniques to estimate the impact of education on the location, scale and shape of the conditional wage distribution.

An Ordering Decision-Making Approach on Spare Parts for Civil Aircraft Based on a One-Sample Prediction

IEEE Access, 2018
Ordering decision-making on spare parts is crucial in maximizing aircraft utilization and minimizing operating costs. This paper develops an approach of ordering decision-making for civil aircraft spare parts based on a one-sample prediction. Engineering

Some Algorithms for the Conditional Mean Vector and Covariance Matrix

Journal of Statistical Software, 2006
We consider here the problem of computing the mean vector and covariance matrix for a conditional normal distribution, considering especially a sequence of problems where the conditioning variables are changing.

The conditional permutation test for independence while controlling for confounders [PDF]

, 2019
We propose a general new method, the conditional permutation test, for testing the conditional independence of variables $X$ and $Y$ given a potentially high-dimensional random vector $Z$ that may contain confounding factors.
