hfetch—319
hconvert d:\haver\haver hdata
The first line creates a new (empty) database named HDATA in the default directory. The second line converts all the data in the Haver database and stores it in the HDATA database.

hfetch |
Command |
|
|
Fetch a series from a Haver Analytics database into a workfile.
hfetch reads one or more series from a Haver Analytics Database into the active workfile.
You must have a Haver Analytics database installed on your computer to use this feature.
Syntax
Command: hfetch(database_name) series_name
hfetch, if issued alone on a command line, will bring up a Haver dialog box which has fields for entering both the database name and the series names to be fetched. If you provide the database name (including the full path) in parentheses after the hfetch command, EViews will read the database and copy the series requested into the current workfile. It will also display information about the series on the status line. The database name is optional if a default database has been specified.
hfetch can read multiple series with a single command. List the series names, each separated by a space.
Examples
hfetch(c:\data\us1) pop gdp xyz
reads the series POP, GDP, and XYZ from the US1 database into the current active workfile, performing frequency conversions if necessary.

hilo |
Command || Graph Command | Group View | Matrix View | Sym View |
|
|
Display high-low[-open-close] graph view of object, or change existing graph object type to high-low[-open-close] (if possible).
Syntax
Command: |
hilo(options) high_ser low_ser [close_ser] |
|
hilo(options) high_ser low_ser open_ser close_ser |
|
hilo(options) arg |
Graph Proc: |
graph_name.hilo(options) |
Object View: |
object_name.hilo(options) |
For a high-low, or a high-low-close graph, follow the command name with the name of the high series, followed by the low series, and an optional close series. If four series names are provided, EViews will use them in the following order: high-low-open-close.
When used with a matrix or group or an existing graph, EViews will use the first series as the high series, the second series as the low series, and if present, the third series as the close. If there are four or more series, EViews will use them in the following order: high- low-open-close. When used as a matrix view, the columns of the matrix are used in place of the series.
Note that if you wish to display a high-low-open graph, you should use an “NA”-series for the close values.
Options
Template and printing options
o= template |
Use appearance options from the specified template. |
|
template may be a predefined template keyword |
|

Examples
hilo mshigh mslow
displays a high-low graph using the series MSHIGH and MSLOW.
hilo(p) mshigh mslow msopen msclose
plots and prints the high-low-open-close graph of the four series.
group stockprice mshigh mslow msclose
stockprice.hilo
displays the high-low-close view of the group STOCKPRICE.
stockprice.hilo(t=templt1)
creates an high-low-close graph view of the group G1, using the settings of the graph object TEMPLT1 as a template.

hist |
Command || Equation View | Series View |
|
|
Histogram and descriptive statistics of a series.
When used as a command or a series view, hist computes descriptive statistics and displays a histogram for the series. When used as an equation view, hist displays a histogram and descriptive statistics of the residual series.
Syntax
Command: hist(options) series_name
Object View: |
object_name.hist(options) |
Options
p |
Print the histogram. |
|
|
Examples
lwage.hist
Displays the histogram and descriptive statistics of LWAGE.

See “Histogram and Stats” on page 308 of the User’s Guide for a discussion of the descriptive statistics reported in the histogram view.
hlabel |
Command |
|
|
Display a Haver Analytics database series description.
hlabel reads the description of a series from a Haver Analytics Database and displays it on the status line at the bottom of the EViews window. Use this command to verify the contents of a Haver database series name.
You must have a Haver Analytics database installed on your computer to use this feature.
hpf—323
Syntax
Command: hlabel(database_name) series_name
hlabel, if issued alone on a command line, will bring up a Haver dialog box which has fields for entering both the database name and the series names to be examined. If you provide the database name in parentheses after the hlabel command, EViews will read the database and find the key information about the series in question, such as the start date, end date, frequency, and description. This information is displayed in the status line at the bottom of the EViews window. Note that the database_name should refer to the full path to the Haver database but need not be specified if a default database has been specified in HAVERDIR.INI.
If several series names are placed on the line, hlabel will gather the information about each of them, but the information display may scroll by so fast that only the last will be visible.
Examples
hlabel(c:\data\us1) pop
displays the description of the series POP in the US1 database.
