Declare a value map object.

Syntax

Command: valmap valmap_name

Follow the valmap keyword with a name for the object.

Examples

The commands:

528—Appendix B. Command Reference

valmap mymap

mymap.append 3 three

mymap.append 99 "not in universe"

declare the valmap MYMAP and add two lines mapping the values 3 and 99 to the strings “three” and “not in universe”.

Declare a var (Vector Autoregression) object.

Syntax

Command: var var_name.ls(options) lag_pairs endog_list [@ exog_list]

Command: var var_name.ec(trend, n) lag_pairs endog_list [@ exog_list]

Declare the var as a name, or a name followed by an estimation method and specification.

The ls (p. 345) method estimates an unrestricted VAR using equation-by-equation OLS. You must specify the order of the VAR (using one or more pairs of lag intervals), and then provide a list of series or groups to be used as endogenous variables. You may include exogenous variables such as trends and seasonal dummies in the VAR by including an “@- sign” followed by a list of series or groups. A constant is automatically added to the list of exogenous variables; to estimate a specification without a constant, you should use the option “noconst”.

See ec (p. 282) for the error correction specification of a VAR.

Options

pPrint the estimation result if the estimation procedure is specified.

530—Appendix B. Command Reference

Syntax

Command: vector(size) vector_name

Command: vector(size) vector_name=assignment

The keyword should be followed by the name you wish to give the vector. You may also provide an optional argument specifying the size of the vector. If you do not provide a size, EViews will create a single element vector. Once declared, vectors may be resized by repeating the command with a new size.

You may combine vector declaration and assignment. If there is no assignment statement, the vector will initially be filled with zeros.

Examples

vector vec1

vector(20) vec2=nrnd

rowvector(10) row3=3

vector vec3=row3

VEC1 is declared as a single element vector initialized to 0. VEC2 is declared as a column vector of size 20 containing a set of draws from the standard normal distribution. Although declared as a column vector, VEC3 is reassigned as a row vector of size 10 with all elements equal to 3.

Wald coefficient restriction test.

The wald view carries out a Wald test of coefficient restrictions for an estimation object.

Syntax

Enter the object name, followed by a period, and the keyword. You must provide a list of the coefficient restrictions, with joint (multiple) coefficient restrictions separated by commas.
