A new arXiv paper introduces a method for linear regression that goes beyond traditional covariance analysis by utilizing higher-order cumulants. This approach allows for the separation and identification of distinct linear effects when an observed regressor is composed of latent components. The research details how fourth-order cumulants can identify slope pairs in a scalar one-confounder model and proposes estimation and inference methods, even in cases of degeneracy where individual slopes are difficult to estimate. For multiple regression, a quadratic tensor recurrence is presented to test for multiple effective coefficient vectors, maintaining signal even when first-order restrictions cancel out. AI
