摘要: Autocorrelation in errors and multicollinearity among the regressors are serious problems regression analysis. The aim of this paper is to examine autocorrelation concurrently compare r − k class estimator generalized least squares estimator, principal components ridge by scalar matrix mean square error criteria linear model with correlated errors.
