The term error-correction infers that the last-period’s deviation from a long-run equilibrium, called the error, influences its short-run dynamics. WebThe explanatory variables were standardized such that the mean value of the shielding constant of the training set and the variance were 0 and 1, respectively. The α parameters of Lasso regression were each fitted to the training set with a model that had α = 10-5, 10-4,...,10 4, 10 5 and selected to minimize the RMSE against the validation set. dr. randolph shey long beach ca
