The development is now at a crucial point in time getting to a certain
"gate". Before the gate is opened EpiData Analysis will be released as
v2.2 and some updates to EpiData Entry will also take place, e.g.
hopefully fixing the reported "auto backup" problem reported.
After the gate there will be a common core system for reading, writing
and interpreting files for as well EpiData Entry, EpiData Analysis and
EpiC. This will not be seen immediately by the end user, but will assure
that all functions are doing the same regardless of which part of
EpiData Software and errors only needs one place for bug fixes. The
translation process will also be adapted and released in common for the
three software parts, since after that all functions and commands in
relation to reading and writing data files and chk files will have the
same number code. The list and translators will be informed when
possible on all of this later this quarter or beginning of next quarter.
Meanwhile EpiData Analysis b161 has been placed for testing for download
from the testing.php page of the main site. (by a mistake the first were
called b160, but actually were b161) - if you report problems report the
date of the build if this was b160).
One new aspect is that one commented by J. Hockin in the Mantis issue
number 335. (A template for SPC graphs in a menu like system): The
technical principle is the following:
A: An htm file is created by the user outside of analysis with a
combination of EpiData Analysis commands and ordinary html coding. (here
B: This file is activated in the help window via an entry in the
graph-spc toolbar menu/dialog.
(the same as the command: helpview "spc.htm")
C: When the user clicks on a given link in the file, certain commands
are issued and information can be given in the output window - without
closing the helpview file.
J.Hockin argues in the Mantis issue that the strange window is difficult
to close again and that it would be preferred to have the spc.htm file
opened in the main results window. I experimented a bit with both
solutions and it turns (to me) an easier approach to use the help window.
This is the same approach used if one uses the menu "Windows->screen
font". Users can develop other htm files for such menu systems and load
them either into help window (helpview spc.htm) or result window (view
spc.htm) and if you wish an easy return to such a file issue the "set
START PAGE " command after which you can open your menu file with F8 or
have the system open it at start of the exe file. For inspiration on
creation of such files, see the startfont.htm and the spc.htm files.
Apart from testing that new menu/command button principle it is
important for us to get tests of the Statistical Process Control Graphs
and the new features introduced. I will contact a number of users
directly, but all are more than welcome to participate.
The optimal is if users would :
a1: Create simple datasets using the built in system accessible via the
toolbar-graph-spc menu/dialog in such a way that the following can be
- freeze (where estimates are based on the first n data points
- breaks (where the time series are split in sub-parts)
- exclude (where individual data points are excluded from estimates)
and the tests (t1-t5), which will show different tendencies/aberrations.
The optimal is to send such datasets in a zip file to "info at
epidata.dk" consisting of the data and the pgm file to run the tests,
including expected results. Disregard the mail notion of the mail not
being received - we will let these through the spam filter and contact

Batch files are fine and easy to automaticly do stuff. Improving the last
coment, I would sugest to put a Warning to press F10 before exit in after
file block or in a before file block in the check file!
Although this may not work 100%, it may help educate and remind the
Abraço forte e que a força esteja com você,
I create many datasets at my hospital and instruct physicians on how to use it. I always add a backup section to my chk files. The problem is that after the user clicks 'save record to disk' and wants to exit, he/she usually clicks the top 'x' on the upper right side of the screen, which is the way most software works. Unfortunately, the backup is not done unless the user clicks the lower 'x'. There is no warning, and backups are not made. Am I doing something wrong? If not, is there a workaround. Failure to make backups has caused me many problems . I am using ver 3.1(120306).
I would really appreciate any help with this problem.
Thank you all

Since previous release of EpiData Analysis quite a few changes have been
implemented. Most of these fall in two groups:
a. Bug fixes of minor (spelling, parsing certain data sets etc) and
major importance. Of major importance are a few in relation to
aggregating data (aggregate and Stattables) and some if statements. Also
some parts of other graphs, e.g. epicurves which would show incorrectly
as connected rectangular bars when outcomes were separated by long periods.
b. Enhancements and further implementation of SPC (Statistical Process
New chart types have been added (xbar-s, uchart , cchart), and further
possibilities of doing proper analysis, e.g. freeze mean and limits
based on first part of data, further warning tests (t4 and t5) and the
setup of variables has been simplified.
Additionaly a new "spc from scratch" menu has been added. You will find
this on the graph toolbar submenu.
c. Translation is now possible. But further documentation and contact to
translators is needed. Users will find the translation tools on the
testing page (in windows and linux versions). Please also test these.
After test and removal of identified bugs this build will be released as
Known issues are: some datasets will give floating point error with
xbar-s - please report on this. The internal validation routines used
here are being updated to a new structure.
Users are highly urged to test the new build and report problems here or
in the feature and bug reporting database.
The test versions are available from: http:\\www.epidata.dk\testing.php
Other changes are expected soon in the documentation with a shift of
core documentation (technical documentation) to a "wiki" based principle.
After v2.2 a quite long period should be expected without new builds
(apart from removal of identified serious bugs). The core parts are
being rewritten to a common form for as well EpiData Entry, Epic and
Analysis. And next test release will be based on this new core for all
Hi to All,
I have a very simple question: when I am trying to export data to
spss, the export menu transform the .rec files into .sps files, ie
syntax and not .sav files, ie data files. Any idea why?
Thanks for your help

I am fairly new to epidata and wonder if someone can give me some advice
on the following task: I am trying to determine if there is any
significance in the difference between the number of days hospital
outbreaks of norovirus last as against the length of community
outbreaks. Is that something I could do in epidata, if so, which
function would I use?

Hello Dr Jean-Francois!
That is the default epidata export to SPSS . if you want to have
access to the file in .sav format, please follow the procedure.
1. Launch your spss software.
2 Go to file menu ->Open-> Syntax.
3. In the syntax window, select all and click on run.
With this steps you can have you files in data file(i.e .sav) instead
of the syntax file.

The explanation is quite simple. SPSS, SAS and other commercial software
companies like M$ are using closed (proprietary) data formats, which
they are not documenting. Therefore we cannot export to .sav format.
This is in contrast to e.g. EpiData or Stata, where the file formats are
fully documented and available for general download. I suggest you write
an e-mail to SPSS and ask why they have a secret data file format. I
would be astonished if they even answered your mail. The system of
closed formats is even more strange. Earlier we had (in my hospital
department) license for SAS for some years (cost around 1200 Euro per
year for one PC) for about what EpiData Analysis can do. And now we
cannot even use our licensed exe files to read the data again......
This is one of the reasons why we develop EpiData Software. ... For
users in extensive need of converting data I suggest to look at the EpiC
utility we develop or you can look at StatTransfer, which is working
quite well and has the policy "once paid - use as long as you like".
