Definition of GCP guidelines and tools
by epidata-list＠lists.umanitoba.ca 08 Jul '06

08 Jul '06

Tim C. Responded: Which set(s) of GCP guidelines is Epidata using as the goal? GCP is an abbreviation of "Good Clinical Practice". The whole issue of GCP guidelines is a difficult one. The preparation in itself involves reading a lot of " heavy legal text". The major issue is that the principles are described in lengthy documents, but there is no strict definition as of what it really implies in terms of specific implementation (apart from the principles). I will add a summary of the main documents later. In the most recent time I have been experimenting with various software tools for the task: - bug tracking - developmental documentation of tasks resolved. - documentation in general - testing and verifying software behaviour - how to accomplish solutions which are operating system independent. ........ To develop all the details of this is going to be a lot of work, which is why collaborative efforts are crucial. One of the issues is persontime and funding and another is testing. As soon as I can reveal more details of the work plan and steps of this process the list will be informed. And interested persons invited to participate. Regards Jens Lauritsen

Q on jumping between fields from related tables
by epidata-list＠lists.umanitoba.ca 03 Jul '06

03 Jul '06

Hi, Would anyone be able to help me figure out how I can jump from one field in a child table to a parent table and back? I have related two files and depending on how the survey questions are answered, I need to be able to go from the child file to the parent table and back. It doesn't seem as if the jump function allows one to jump from one field in one table to another field in a different (but related) table. Any help would be greatly appreciated.

bug tracking possibility - new system in test
by epidata-list＠lists.umanitoba.ca 28 Jun '06

28 Jun '06

In the preparation for compliance with GCP guidelines and general handling of the 2006-2010 development plan it is important to document bugs and issues resolved. A new bug tracking system is in test. Anyone who wishes to participate can sign on as reporter at : http://www.epidata.dk/php/mantis Following the testing further setup is required before the site will be operational: e.g.: definition of categories definition of projects definition of maintainers/managers etc. It the system is approved, then a cleanup will be made before final and further usage. But to me it seems as if the maintenance, running and using of the system should be easy. A few other options has been considered, but they seemed to detailed for the purpose. Kind regards Jens Lauritsen EpiData Association

EpiTables
by epidata-list＠lists.umanitoba.ca 17 Jun '06

HI, I am trying to run an EpiTable on some basic food exposure data where 1=Ate the food item, 2=did not eat food item. However when I run the EpiTable it is automatically assuming that the exposure variable is 2 (ie.e not eating food item). How can I change the exposure variable to 1? ----------------------------------------- ******************************************************************* ******* The information contained in the EMail and any attachments is confidential and intended solely and for the attention and use of the named addressee(s).

searching during entry and development issues
by epidata-list＠lists.umanitoba.ca 12 Jun '06

12 Jun '06

On april 1st. Shavinder Singh questioned about searching principles Actually I see the comment as a wish for this: a. When searching the specification should be done in the same form as where entry is done instead of using a specific search form. b. Apart from showing the next record matching the search criteria all records matching the criteria should be shown in the same form as with AUTOSEARCH c. Or as an alternative to b, show one record at a time and find next one with F3. Clarification of issues like this will be part of the coming development plan. Including possible planning a user survey on usage etc. Comments and views welcomed. Regards Jens Lauritsen EpiData Association

Convert sting to numeric - Epidata Analysis
by epidata-list＠lists.umanitoba.ca 09 Jun '06

09 Jun '06

Hello How is it possible to convert a string to a numeric value in Epidata Analysis. I have tried all the proposed solutions found on the support list, but the result is always the same 'data type mismach" I have a string variable like var1 = GHXXXXX15 And I want to make statitic(median, means ....) on the last part (15) , I can convert to a numeric value. The function to convert numeric to string exists, but no string to numeric.

Website now in Spanish also - try www.epidata.dk/sp and other good news
by epidata-list＠lists.umanitoba.ca 05 Jun '06

05 Jun '06

*Website in Spanish (Español) *31. May 06 Due to the work of Pedro Arias and with some assistance from Juan Carlos Merino (Peron) the whole website has been translated to Spanish. Other translations can be placed if someone wishes to translate parts or all. A bit later we will arrange for a news section for the translated version also. ................................................................................................................. Good news - funding received - Financing the conversion plan A first donation of roughly 7000 Euro has been received for the development plan from a Danish Medical research fund. Experimentation with possible principles for implementation of aspects of "audit trail" will start soon based on the funding. I will add a "counter" indicating at all times what percentage of the plan is currently financed. ................................................................................................................

Re: Sumfreq and Sumtables
by epidata-list＠lists.umanitoba.ca 03 Jun '06

03 Jun '06

I propose that the principle be established that any appropriate command will eventually allow weights via /w=varname To simplify syntax for many users, /sum=varname can be a synonym for /w=varname on the FREQ command and TABLES command We do not need separate sumfreq and sumtables commands. I never liked this in EpiInfo because you had to learn another command syntax and EpiInfo wasn't know for consistency of syntax. It is good practice to use the variable name COUNT (in English at least) whenever dealing with aggregated data. This becomes self documentation. We do this with an in house system for managing monster national data sets, but still will get people creating frequency tables that do not sum the COUNT variable and they wonder why every category has a frequency of 1 Jamie Hockin Public Health Agency of Canada
