Dear Jens,
Thanks for your helpful comment on creating an identifiant from various
variables and double data entry (see below).
I just wanted to clarify a few things:
1) Does this mean that when using the 'Double Entry Verification' option
(immediate comparison), this will not work if you have added any new
variables into the .rec, or changed the order of the variables from the
existing .rec?
2) If you use the other method of data verification (entering data into
two seperate files and then validating duplicate files afterwards), is it
possible to compare the old and new .rec files, even if a new variable has
been added, or the order of the variables has been changed?
Will using the 'validate duplicate files' option work if the new .rec file
has the variables in a different order?
Thanks so much for all your help,
Nicki Bailey
One aspect of this about unique identifiers is when users want to do
double entry.
The only double entry option in this situation is to enter the data
twice and then compare afterwards, since the "immediate comparison"
double entry mode is not available for combined field unique entries
unless the records are entered in EXACTLY the same sequence as the first
time. The problem for the user is, that the system is NOT giving correct
warnings in the immediate double entry if the unique index is created in
contrast to entered directly.

Dear all,
I have a question about linking the follow-up round of a survey to the
baseline which was data entered using EpiData. The follow-up is a new
database that will be linked to the baseline during analysis. During data
entry, I want to make sure that the IDs entered in the follow-up match those
from the baseline in the household roster of the survey. No member that was
in the household in the baseline should be missing, however new members can
be added to the household. I have villageid, householdid, and personid,
each of which is entered separately. I can then create a unique id which
combines these to ID the unique individual.
The baseline data was entered using double data entry where the data was
compared dynamically (Menu Option: "Double Entry verification") and the
follow-up will be done in the same manner. The survey is large and the data
are entered on several different computers that are not networked.
The only way I can think of to link the follow-up to the baseline in order
to compare the IDs would be to do a mini double data entry after the first
data entry of the household roster where I check only the IDs for the data
and see what is in the follow-up that isn't in the baseline, but this seems
like a poor solution. I would prefer to do something dynamic, which 1)
doesn't allow the data entry clerk to move on to another household until
they have entered all of the IDs from the baseline and 2) flashes a warning
if there is an ID entered that does not match with the baseline. I don't
think that EpiData has these capabilities. Please let me know if I am
simply not educated enough in this software.
Thank you for your help (and I apologize for this long posting).

Dear All
Due to several requests the list will from now on send password
reminders from time to time. You can go into the list specification and
turn this on (after you receive the first reminder).
It would be constructive for the development of the Core module if users
could find some time to challenge the core-module-test application in
Linux or Windows. See www.epidata.dk/testing.php
Report success and/or failures to the list.

Jose,
Well, I would say that You could use a softaware such as stattransfer which
would solve this problem. If you dotnt have it, I would recomend any other
statistical software is usually able to do so. I usually work with stata or
R.
With stata you may save he spreadsheet as csv or tb separeted and import
within stata and save in stata format.
With R is even more simple because thereis some packages that are able to
import directly from xls and then save it in stata format or dbf format.
Usually stata format is the most friendly for epidata entry. If you dont
have any experience with R, perhaps you will find easier to use a grphical
interface such as Rcmdr or pmg. To install the Rcmdr and use R with a
graphical interface, after installing it type
"install.packeges("Rcmdr")" and afer the install type "library("Rcmdr")" The
rest should be more intuitive!
Abraço forte e que a força esteja com você,
Pedro Emmanuel
Dear member in the group
is there any way to export data from Excel 2007
that can be read with Epidata. I have found the
excel 2007 does not export to dbf format.
I will appreciate any help.

hi
Has anyone figured out how to enter GPS coordinates in Epidata in a
form which preserves the structure so that they can be exported to
another program for analysis? Thanks in advance for any help,
Susie Foster
