We propose a consistent estimator of the rank of the coefficient matrix and achieve …
The most basic statistical model for the relationship between a covariate vector and a response variable is the linear model where is an unknown parameter vector, and is random noise with mean zero and variance . Given independent responses , with corresponding covariates , from this model, we can form the response vector , and design matrix . When and th… WebDriven by a wide range of applications, high-dimensional linear regression, where the dimension p can be much larger than the sample size n, has received significant recent attention.
