Dear Leticia Grize
Your questions are as well relevant and very much to the point of what
we are all asked from our IT-departments. E.g. from the IT-department in
the health region where I work at a University Hospital.
I think the tendency for all Health Regions, Non-profit organizations
like yours, hospitals in general and universities is to impose very
strict control on which software may be installed.
Therefor allow me to give a quite lengthy explanation.
The EpiData Association does not have a larger organization and it is
quite impossible within the means we have and the time constraints to
adopt, e.g. as well a Microsoft developer account, a qualification for
the Mac (Apple environment) and also secure standard open-source
principles for the Linux users. Another issue is whether we would
actually approve of such a principle (Microsoft/Apple) - the answer is
Based on your other questions I will add a few comments:
1. Never use test versions for production. The file structure might
change, such that you cannot use it in future public release versions.
We clearly warn against such use on the development pages.
2. For production/real projects only use software from
3. The current public production versions are:
Maintained and continously developed software:
*OS:* _Manager_ *v188.8.131.52* _EntryClient_ *v184.108.40.206* _Analysis_
Software which is available, but will NOT be developed further:
EpiData Classic: Analysis V2.2 Rel. 3 (Build 187 ) EpiData Classic
*3.1 * Build: (* (27jan2008)*
As long as the v3.1 works to the satisfaction and sufficient function it
is a very strong tool and widely use. In relation to analysis there are
good reasons to use Analysis Classic v2.2. until the rewritten Analysis
(now at v1.2.2.) can do the same analysis. Another aspect is that for
some commands the syntax is a bit more difficult - due to principles of
maintenance of the software for the three operating systems (Linux,
Windows and Mac).
We DO NOT suggest that new users use the Classic Software 3.1, since the
principles of rec+chk file is no longer maintained. This is now replaced
with the epx (XML) based file principles and for most uses of data
definition and entry the functionality of Manager and EntryClient is
much preferred in modern OS, e.g. Windows 10, Mac or Linux. And user
logging principles and encryption of data has been implemented in the
If you look in the archives of this mail-list you may see many documents
on the development principles, the roadmap and the phases of coming
In short what are the plans:
Basically I DO NOT expect to develop Manager and EntryClient with more
functionality than what you have now - bugs will be fixed obviously,
like just now we identified a bug in the "Unarchive" tool found in
EpiData Manager, which will lead to a new version on the public
For EpiData Analysis (v 1.2.2) the datamanagement functions are almost
in place, more analysis commands are coming, a graph module and more
specific adaptations to enhanced functionality for routine automatic
analysis will come. Towards the end of development I also hope that we
will be able to simplify some of the aspects, which are now a bit tricky
In relation to testing new public versions and implemented principles we
have the following:
a. See the page http://www.epidata.dk/documentation.php.
b. For analysis a validation package compares all estimates with
reference values that we take either from Stata or a reference data
analysis commands from the NIST system. We have more than 1000 tests
being done in batch mode. An example report is here:
c. For Manager we have a spreadsheet with quite many tests that are done
manually every time before release of a new public version.An example
report is here:
So all in all - I think users (and possibly IT-departments) will accept
and acknowledge that EpiData Software is a quite comprehensive addition
to public health, clinical research and project management. And also
that we have quite extensive quality assurance and version control
Please also ask your IT-department to compare the costs of attaining the
EpiData software with the expectations (donations for further aspects
Finally I suggest that you look at the very instructive course material
available at this address. All based on the new software and for
analysis the EpiData Classic. This is done thanks to Hans Rieder with
moderate input from me and others. https://tbrieder.org/epidata/epidata.html
