The DATAVIEW Statistical Information System is an integrated software package that permits the
management, display and detailed analysis of time-related data. The package provides comprehensive
time series data base maintenance facilities, a variety of statistical analysis facilities,
automatic frequency conversion, high quality screen and hard-copy graphics displays, and powerful
report generation capabilities, including direct links to spreadsheet and desktop publishing or
advanced word processing packages. Both analytical and presentation quality graphs can be produced easily.
Among its statistical analysis options, DATAVIEW supports multivariate regression, seasonal adjustment,
and correlation analyses, thus allowing the relationship between variables to be examined in depth;
the regression options include the capability to specify a wide range of functional forms and use
The package supports both interactive and macro processing, thus permitting both immediate and
periodic follow-up analyses. Production routines can be organized to generate virtually all types
of output, including tabular reports, graphs, and repetitive analyses that incorporate new data
as they become available.
DATAVIEW can be licensed as a single system or in quantity. All prices include one year's updates,
improvements, and unlimited telephone/Email support. On-site training can be provided and an optional
annually renewable AlphaPlus support agreement is available that provides support, updates, and
improvements in the second and subsequent years.
The program runs on standard Wintel-compatible microcomputers, including notebooks and sub-notebooks. Compatible with Windows XP, Windows 7 and Windows 8. A version designed specifically for use with Windows 10 will be released shortly. Legacy support for earlier operating systems is also available.
DATAVIEW offers scalable time series data base maintenance facilities equal to the demands of
any likely task. To provide flexibility and security, it permits the creation and maintenance
of both permanent data banks and temporary workspace (Memory) files. Each data bank can contain
as many as 10,000 time series, each with a maximum of 1600 observations; as many as 15 such data
banks can be accessed simultaneously. Memory Files can store up to 500 series with the same
characteristics. In addition, powerful import and export facilities are available to permit
the transfer of data between DATAVIEW and other environments, including both government sources,
vendors who supply data bases in its native data bank format, and the multiplicity of Internet
Internally, DATAVIEW provides an extensive set of data management functions, operators and
features, including Census X-11 quarterly and monthly seasonal adjustment, as well as a wide
range of mathematical, statistical, relational, and logical operators; optionally MODLER also
supports weekly seasonal adjustment. The platform has the further capability to generate easily
such analytic aids as pseudo random variates, correlation matrices and several types of growth
triangles. The standard data observation frequencies include weekly, bi-weekly, ten day, lunar,
monthly, bi-monthly, quarterly, semi-annual, annual, and various fiscal and agricultural year
frequencies. Under user control, automatic frequency conversion is fully supported.
DATAVIEW offers a number of access aids. Data Banks and Memory Files are all component-level
documented. Moreover, this documentation, which includes that for individual series, can be
displayed whole or in part in order to assist in the identification and retrieval of these series.
In addition, both series names and documentation can be keyword searched to find particular items.
Index and Find buttons appear on dialogue boxes whenever such information is likely to be helpful.
As appropriate, a Macro button also appears to allow macro file segments to be included in current
commands, thus obviating needless re-keying, not to mention context specific help.
Presentation quality data display features include line graphs, bar charts, dated points,
mixed line-bar, and stacked bar charts. Each may be specified as plots of one or more series
or expressions against time, or as plots of series or expressions against some other series.
Log and semi-log scale plots are supported as well as plots with dual y-axis scales, grid
lines and other features. Full screen editing of screen graphics displays is also supported,
allowing labels, notes and comments to be placed anywhere. In addition, displays may be saved,
generally to the Clipboard, but also JPG, GIF and other such files in order to integrate both
text and graphics into reports or support the generation of Web pages. It is additionally
possible to autogenerate template macros that permit graphs to be reproduced later using the
same or an updated data set.
Within MODLER, the report generation facilities permit the creation of various types of tables,
including both mixed frequency and those with embedded formulas for row and column oriented
transformations. These features may be combined. Tables may include titles, subtitles (left
justified, right justified, or centered), and blank lines. Tables and portions of tables may
be set off with ruling lines. In general, the tables produced are time-labelled, with dates
usually displayed horizontally, although transposed tables can also be produced. Such tables
may show successive observations or selected observations for even widely separated dates.
A particular MODLER feature is the capability to directly address the cells of a standard
spreadsheet, thus permitting time series observations to be copied to those cells or retrieved.
Such observations may be converted on-the-fly from one observation frequency to another; it is
also possible to embed transformations, so as to copy the results of those transformations to
the spreadsheet cells. This facility permits the creation of tabular reports instantly that
otherwise would require extensive spreadsheet macro programming. It may be operated interactively
or templates (macros) may be created more or less as an automatic by-product and used repeatedly
MODLER also produces specialty tables, such as solution comparison tables, displaying differences
and percentage differences variable-by-variable for different model solutions. Other specialty
tables display standard error statistics.
The regression methods currently supported include:
- Ordinary Least Squares
- Restricted Least Squares
- Ordinary Ridge Regression
- Weighted Least Squares
- Generalized Least Squares
- Two Stage Least Squares
- Polynomial Distributed Lags
- Autoregressive corrections
These options may be combined whenever the algorithmic operations involved are inherently
compatible. Furthermore, commands may include embedded expressions that can even combine
mathematical, logical, relational, and statistical operators and functions, both for dependent
and regressor variables.
The usual range of supporting regression statistics and tests are provided, including the
basic t-statistics, R2, and Durbin-Watson, plus a very wide range of other useful statistics
such as the Log Likelihood function, Durbin h, Schwarz Criterion, Akaike Information Criterion,
and tests such as unit root, structural stability and specification tests. MODLER also
incorporates various estimation support facilities, including regressor term DROP and ADD
commands, the capability to save residual and predicted sample period values, and provisions
for making disk or hard copies of most displays; it is also possible to archive both commands and
MODLER is evolutionary in its offerings but is not intended to be a specialty regression
package; by design, its focus is on the standard methods commonly used for simultaneous
equation models. However, its data link facilities encourage, permit and support the
joint use of specialist packages such as MicroFit, TSP, and LimDep, thus offering its
users the best of both worlds.
As indicated earlier, DATAVIEW is designed to be used with other software, both other members of
its own software family and third party packages: data can be imported and exported using
standard data interchange file formats, both fixed field and comma separated, including ASCII,
Lotus 1-2-3, and TSD. It can also directly read from and write to spreadsheet cells.
DATAVIEW's DataClp technology additionally permits the capture of text based data from web pages,
textfiles and other sources. This facility is extremely flexible in operation: the files can
take the form of documents or those that are formatted as data tables. As indicated, they can
be located on your machine or they may originate as Internet Web pages. The observations can
be captured singly or as a chronological group.
As needed, DATAVIEW can also be network integrated into corporate data based systems that are
based on standard DBMS technologies, although this generally requires specific customization.
Virtually all forms of DATAVIEW output can be incorporated into textual reports, spreadsheet
tables, and other displays. Data can be directly copied cell-by-cell to spreadsheet files,
and to the files of other relevant number-oriented packages. Provisions also exist to export
directly to desktop publishing and advanced word processing packages; the packages specifically
supported include Pagemaker, Ventura Publisher, Word, Word Pro, and Word Perfect. Custom
versions of DATAVIEW are also available that support professional publishing systems.
Depending upon the specific application, DATAVIEW can be operated either using commands or
the Windows interface by means of menus, icons, and dialog boxes. Using these Windows
facilities, it is also possible to generate automatically macro commands that can be captured
in order to perform repetitive periodic operations. In general, commands can be entered
interactively or formed into macros that can be preserved from one session to the next.
Users who have programming skills, or access to these, can also create programs using
Visual Basic, Delphi, or even programming languages such as C/C++ or Fortran, that incorporate
DATAVIEW offers several types of online help facilities, both general and context specific.
The standard help file offers multiple help levels, so as to provide the appropriate amount
of help needed in each individual case; application specific help files can be organized in
the same way. Users can produce hard copy using the incorporated Print command and can also
annotate and otherwise personalize the help pages.
