490—Appendix B. Command Reference

Examples

series lwage=log(wage)

stomna(lwage,vec1)

converts the series LWAGE into a vector named VEC1 using the current workfile sample. Any NAs in LWAGE will be placed in VEC1.

group rhs x1 x2 x3

sample s1 1951 1990

stom(rhs,x,s1)

converts a group of three series RHS to a matrix named X using sample S1. The matrix X will always have 40 rows and 3 columns.

store

Command || Pool Proc

 

 

Store objects in databases and databank files.

Stores one or more objects in the current workfile in EViews databases or individual databank files on disk. The objects are stored under the name that appears in the workfile.

When used as a pool proc, EViews will first expand the list of series using the pool operator, and then perform the operation.

Syntax

Command:

store(options) object_list

Pool Proc:

pool_name.store(options) pool_ser1 [pool_ser2 pool_ser3 ...]

Follow the store command keyword with a list of object names (each separated by a space) that you wish to store. The default is to store the objects in the default database.

(This behavior is a change from EViews 2 and earlier where the default was to store objects in individual databank files).

You may precede the object name with a database name and the double colon “::” to indicate a specific database. You can also specify the database name as an option in parentheses, in which case all objects without an explicit database name will be stored in the specified database.

store—491

When used as a command, you may use wild card characters “?” (to match any single character) or “*” (to match zero or more characters) in the object name list. All objects with names matching the pattern will be stored. You may not use “?” as a wildcard character if store is being used as a pool proc, since this conflicts with the pool identifier.

You can optionally choose to store the listed objects in individual databank files. To store in files other than the default path, you should include a path designation before the object name.

Options

d=db_name

Store to the specified database.

 

 

i

Store to individual databank files.

 

 

1 / 2

Store series in [single / double] precision to save space.

 

 

oOverwrite object in database (default is to merge data, where possible).

g=arg

Group store from workfile to database: “s” (copy group

 

definition and series as separate objects), “t” (copy

 

group definition and series as one object), “d” (copy

 

series only as separate objects), “l” (copy group defini-

 

tion only).

 

 

If you do not specify the precision option (1 or 2), the global option setting will be used. See “Database Registry / Database Storage Defaults” on page 938 of the User’s Guide.

Examples

store m1 gdp unemp

stores the three objects M1, GDP, UNEMP in the default database.

store(d=us1) m1 gdp macro::unemp

stores M1 and GDP in the US1 database and UNEMP in the MACRO database.

store usdat::gdp macro::gdp

stores the same object GDP in two different databases USDAT and MACRO.

store(1) cons*

stores all objects with names starting with CONS in the default database. The “1” option uses single precision to save space.

492—Appendix B. Command Reference

store(i) m1 c:\data\unemp

stores M1 and UNEMP in individual databank files.

structure

Sspace View

 

 

Display summary of sspace specification.

Show view which summarizes the system transition matrices or the covariance structure of the state space specification. EViews can display either the formulae (default) or the values of the system transition matrices or covariance.

Syntax

Sspace View:

sspace_name.structure(options) [argument]

If you choose to display the values for a time-varying system using the “v” option, you should use the optional [argument] to specify a single date at which to evaluate the matrices. If none is provided, EViews will use the first date in the current sample.

Options

vDisplay the values of the system transition or covariance matrices.

c

Display the system covariance matrix.

 

 

p

Print the view.

 

 

Examples

ss1.structure

displays a system transition matrices.

sur—493

ss1.structure 1993q4

displays the transition matrices evaluated at 1993Q4.

sur

System Method

 

 

Estimate a system object using seemingly unrelated regression (SUR).

Note that the EViews procedure is more general than textbook versions of SUR since the system of equations may contain cross-equation restrictions on parameters.

Syntax

System Method: system_name.sur(options)

Options

i

Iterate on the weighting matrix and coefficient vector

 

simultaneously.

 

 

sIterate on the weighting matrix and coefficient vector sequentially.

o (default)

Iterate only on the coefficient vector with one step of

 

the weighting matrix.

 

 

cOne step iteration on the coefficient vector after one step of the weighting matrix.

m=integer

Maximum number of iterations.

 

 

c=number

Set convergence criterion.

 

 

l=number

Set maximum number of iterations on the first-stage

 

iteration to get one-step weighting matrix.

 

 

showopts /

[Do / do not] display the starting coefficient values and

-showopts

estimation options in the estimation output.
