High dimension linear regression
WebWe propose two variable selection methods in multivariate linear regression with high-dimensional covariates. The first method uses a multiple correlation coefficient to fast reduce the dimension of the relevant predictors to a moderate or low level. The second method extends the univariate forward regression of Wang [ (2009). WebAbstract Linear regression models with stationary errors are well studied but the non-stationary assumption is more realistic in practice. An estimation and inference procedure for high-dimensional... Skip to Article Content; Skip to Article Information; Search within. Search term. Advanced Search Citation Search. Search term.
