The shared confounder assumption posits that the … WebStandard high-dimensional regression methods assume that the underlying coe cient vector is sparse. This might not be true in some cases, in particular in presence of hidden, confounding variables. Such hidden confounding can be represented as a high-dimensional linear model where the sparse coe cient vector is perturbed. For this …
