Thus, if a user first displayed a multiple graph of impulse responses and then wanted to show the results in a table, or perhaps display a subset of those original responses, the procedure would have to be respecified and recomputed from the beginning. The prior impulse response interface coupled the choices for which impulses and responses to display and the method in which they were displayed, with the various options for computing the impulse response and standard error. estimation with observation and variable weights.ĮViews 12 features a new interface for computing and displaying impulse responses and confidence intervals for VAR and VEC estimators.new diagnostics showing training-test set cross-validation composition.new cross-validation options for selecting penalty function including rolling and expanding window methods for selecting training and test sets.When multiple parameters are used, EViews also supports options for automatic generation of penalization parameters, as well as cross-validation tools for choosing the parameter with the lowest error.ĮViews 12 offer a number of additions to the existing toolkit: EViews supports estimation over a single lambda penalization parameter and a grid search over multiple penalization parameters.
Depending on the particular parameters chosen for the elastic net model, some or all of the regressors are preserved, but their magnitudes are reduced.ĮViews 11 includes tools for estimation of elastic net, ridge, and Lasso regression models. These new features allow you to use the General-to-Specific (GETS) method for variable selection and indicator saturation.Įlastic net regularization is a popular solution to the overfitting problem, where a model fits training data well but does not generalize easily to new test data. The goal of the MIDAS approach is to incorporate the information in the higher frequency data into the lower frequency regression in a parsimonious, yet flexible fashion.ĮViews 12 extends the existing MIDAS toolbox by adding additional estimation options. More specifically, the MIDAS methodology addresses the situation where the dependent variable in the regression is sampled at a lower frequency than one or more of the regressors. MIDAS is an estimation technique which allows for data sampled at different frequencies to be used in the same regression.
Mixed Data Sampling (MIDAS) regression was introduced in EViews in earlier versions. Select the Auto-detect check box in the Outlier/indicator saturation area on the right-hand side of the dialog, and then press the Options tab to bring up the Indicator Options dialog: Next, click on the Options tab to display the dialog: To instruct EViews to detect indicators in your least squares regression, open the equation estimation dialog, enter your least squares specification in the Equation specification edit field, and select LS – Least Squares (NLS and ARMA) in the Method dialog. The indicator saturation approach works by including indicator variables for outliers or structural breaks at every observation in the regression, and then employing the GETS algorithms to select which of the included variables should be retained in a final regression model. The indicator saturation approach is an extension of least squares regression for testing for outliers and structural breaks in a regression specification. Indicator Saturation in EviewsĮViews 12 have added regression tools for testing outliers and structural breaks in a regression specification based on the indicator saturation approach. Following the variable selection process, EViews reports the results of the final regression. Before estimation, you must specify a dependent variable together with a list of always-included variable, and a list of selection variables, from which the selection algorithm will choose the most appropriate. EViews includes three such techniques: Stepwise, and (new to EViews 12) Lasso and Auto-Search/GETS.Įach of these techniques are implemented in EViews as a pre-estimation step before performing a standard least squares regression. EViews is best at automatically determining the variables to be used as regressors in a least squares regression. Selecting variables, among a large set of all variables, that are to be included in models is a very important step in analysis. EViews 12 has come up with many econometric advancements making your analysis more accurate and less time-taking.
