Object Declaration |
|
|
Declare a model object.
Syntax
Command: model model_name
The keyword model should be followed by a name for the model. To fill the model, you may use append (p. 205) or merge (p. 368).
Examples
model macro
macro.append cs = 10+0.8*y(-1)
macro.append i = 0.7*(y(-1)-y(-2))
macro.append y = cs+i+g
declares an empty model named MACRO and adds three lines to MACRO.

name |
Graph Proc |
|
|
Change the names used for legends or axis labels in XY graphs.
Allows you to provide an alternative to the names used for legends or for axis labels in XY graphs. The name command is available only for single graphs and will be ignored in multiple graphs.
Syntax
Graph Proc: |
graph_name.name(n) legend_text |
Provide a series number in parentheses and legend_text for the legend (or axis label) after the keyword. If you do not provide text, the current legend will be removed from the legend/axis label.
Examples
graph g1.line(d) unemp gdp
g1.name(1) Civilian unemployment rate
g1.name(2) Gross National Product
372—Appendix B. Command Reference
The first line creates a line graph named G1 with dual scale, no crossing. The second line replaces the legend of the first series UNEMP, and the third line replaces the legend of the second series GDP.
graph g2.scat id w h
g2.name(1)
g2.name(2) weight
g2.name(3) height
g2.legend(l)
The first line creates a scatter diagram named G2. The second line removes the legend of the horizontal axis, and the third and fourth lines replace the legends of the variables on the vertical axis. The last line moves the legend to the left side of the graph.

nnfit |
Group View |
|
|
Nearest neighbor fit.
Displays the fit of the second series (vertical axis) on the first series (horizontal axis) in the group.
Syntax
|
Group View: |
group_name.nnfit(options) |
Options |
|
|
|
|
|
|
b=fraction |
Bandwidth as a fraction of the total sample. The larger |
|
(default=0.3) |
the fraction, the smoother the fit. |
|
|
|
|
d=integer |
Degree of polynomial to fit. |
|
(default=1) |
|
|
|
|
|
b |
Bracket bandwidth span. |
|
|
|
|
x |
Exact (full) sampling. Default is Cleveland subsam- |
|
|
pling. |
open—373
integer |
Approximate number of data points at which to com- |
(default=100) |
pute the fit (if performing Cleveland subsampling). |
|
|
u |
No local weighting. Default is local weighting using |
|
tricube weights. |
|
|
m=integer |
Set number of robustness iterations. |
|
|
s |
Symmetric neighbors. Default is nearest neighbors. |
|
|
s=name |
Save fitted series. |
|
|
p |
Print the view. |
Examples
group gr1 gdp90 gdp50
gr1.nnfit(x,m=3)
displays the nearest neighbor fit of GDP50 on GDP90 with exact (full) sampling and 3 robustness iterations. Each local regression fits the default linear regression, with tricube weighting and a bandwidth of span 0.3.
group gro1 weight height
gro1.nnfit(50,d=2,m=3)
displays the nearest neighbor fit of HEIGHT on WEIGHT by fitting approximately 50 data points. Each local regression fits a quadratic, using tricube robustness weights with 3 robustness iterations.

open |
Command |
|
|
Opens a program file, or text (ASCII) file.
This command should be used to open program files or text (ASCII) files for editing.
You may also use the command to open workfiles or databases. This use of the open command for this purposes is provided for backward compatibility. We recommend instead that you use the new commands wfopen (p. 532) and pageload (p. 392) to open a workfile, and dbopen (p. 266) to open databases.
374—Appendix B. Command Reference
Syntax
Command: open(options) [path\]file_name
You should provide the name of the file to be opened including the extension (and optionally a path), or the file name without an extension but with an option identifying its type. Specified types always take precedence over automatic type identification. If a path is not provided, EViews will look for the file in the default directory.
Files with the “.PRG” extension will be opened as program files, unless otherwise specified. Files with the “.TXT” extension will be opened as text files, unless otherwise specified.
For backward compatibility, files with extensions that are recognized as database files are opened as EViews databases, unless an explicit type is specified. Similarly, files with the extensions “.WF” and “.WF1”, and foreign files with recognized extensions will be opened as workfiles, unless otherwise specified.
All other files will be read as text files.
Options
p |
Open file as program file. |
|
|
t |
Open file as text file. |
|
|
type=arg |
Specify text or program file type using keywords. |
(“prg” or “txt”) |
|
|
|
Examples
open finfile.txt
opens a text file named “FINFILE.TXT” in the default directory.
open "c:\program files\my files\test1.prg"
opens a program file named “TEST1.PRG” from the specified directory.
open a:\mymemo.tex
opens a text file named “MYMEMO.TEX” from the A: drive.
Cross-references
