method = arg | Stepwise regression method: “stepwise” (default), “uni” (uni-directional), “swap” (swapwise), “comb” (combinatorial), “gets” (auto-search/GETS), “lasso” (Lasso). |
nvars = int | Set the number of search regressors. Required for swapwise and combinatorial methods, optional for uni-directional and stepwise methods. |
w=arg | Weight series or expression. Note: we recommend that, absent a good reason, you employ the default settings Inverse std. dev. weights (“wtype=istdev”) with EViews default scaling (“wscale=eviews”) for backward compatibility with versions prior to EViews 7. |
wtype=arg (default=“istdev”) | Weight specification type: inverse standard deviation (“istdev”), inverse variance (“ivar”), standard deviation (“stdev”), variance (“var”). |
wscale=arg | Weight scaling: EViews default (“eviews”), average (“avg”), none (“none”). The default setting depends upon the weight type: “eviews” if “wtype=istdev”, “avg” for all others. |
coef=arg | Specify the name of the coefficient vector (if specified by list); the default behavior is to use the “C” coefficient vector. |
prompt | Force the dialog to appear from within a program. |
p | Print estimation results. |

nlambdas=arg (default=100) | Number of lambas for EViews-supplied list. |
s | Use the current coefficient values in estimator coefficient vector as starting values (see also
param). |
s=number (default=1) | Specify a number between zero and one to determine starting values as a fraction of OLS values (out of range values are set to “s=1”). |
maxit=integer | Maximum number of iterations. |
conv=scalar | Set convergence criterion. The criterion is based upon the maximum of the percentage changes in the scaled estimates. The criterion will be set to the nearest value between 1e-24 and 0.2. |
showopts / ‑showopts | [Do / do not] display the starting coefficient values and estimation options in the rotation output. |
coef=arg | Specify the name of the coefficient vector (if specified by list); the default behavior is to use the “C” coefficient vector. |
lambda=arg | Value of the penalty parameter. Can be a single number, list of space-delimited numbers, a workfile series object, or left blank for an EViews-supplied list (default). Values must be zero or greater. |
w=arg | Weight series or expression. |
