Hi Charity and Lars: There are two ways for duplicate data entry: 1) independent of sequence 2) dependent on sequence 1) If you use a field with unique identifier, you can enter the data independently of sequence twice, and then compare the two files later on that unique identifier. In this instance two data entry groups can enter add the same time part A and part B and then switch for second entry. 2) You can use the "Tools" "Prepare Double Entry Verification". If you do not tick and choose the option "Match records by field" (and choose the Unique identifier), then the second entry will by default follow the record number, and thus sequence matters. If you choose that option, the first data entry group will still have to await completion by the first data entry group. As Charity says, it is critical in any case to have a truly unique identifier which can by assured by KEY UNIQUE. Seemingly, Lars, you did not have that. You must thus identify the records with duplicate identifiers and or missing identifiers in both files, mark them for deletion (but not packing" and then compare. You deal then separately with the problematic records in both files, most simply perhaps by reentering them properly and independently in both files. Regards, Hans Hello Lars, I just did a small test of this to make sure, and the ordering/sequence of IDs in the two files does not make a difference when Validating Duplicate Files. What will cause a problem is if there is a duplicated ID in one of your two files - are you sure that the Case IDs are unique? You should have "KEY UNIQUE 1" included in your .chk file for the ID variable to ensure this.

Validation duplicate files

Dear Epidata_list, I'm a new member of this list and a fairly new user of the Epidata software. In attempting to validate duplicate files not entered in same sequence by two observers I have difficulty in performing the test under documebt/validate duplicate files. Attempting to perfom the test with a selected key field of case-id an error is given; "Duplicate keys found" and the validation is terminated. Is it possible to perform a comparison of the two datasets despite the fact that the registrations are not performed in same sequence with regard to registration of the observations?

Re: Release of EpiData Analysis v2.0 for testing
by epidata-list＠lists.umanitoba.ca 01 Feb '07

01 Feb '07

As announced a short while back the module is now available for testing. A short example should help users getting started on the test. 1. Expect that some/many set commands have changed. E.g. Obsolete ones in version 2: Set statistics, set percentages, set table reverse etc 2. You only get what you ask for. e.g.: tables v1 v2 // will only give the counts tables v1 v2 /R // will give row percentages (column:/C, total: /T) tables v1 v2 /T /EX // will give a chi square test and with /EX also exact tests for 2x2 tables tables v1 v2 v3 /T /EX // will do a stratified analysis with overall exact testing as well. tables v1 v2 v3 v4 /OA //will make a condensed outbreak analysis table tables v1 v2 /SD // will sort descending instead of the default ascending sort on row and column tables v1 v2 /SRAT // will sort ascending on the row total /SRDT would be descending 3. replacement for epitables or etab will be typically (to have highest value as case and exposure): tables v1 v2 v3 /sd /t Many aspects are not final yet - notice it is a test build, e.g. some issues remain on medians in SPC graphs. Therefore the front page also states: Notice - this is a premature test build - only for experienced test persons ! regards Jens Lauritsen EpiData Association

EpiData Analysis: testing of version 2.0.1.104
by epidata-list＠lists.umanitoba.ca 01 Feb '07

01 Feb '07

Public testing of version 2 of EpiData Analysis can now begin. A lot of work has been done to reshape internal parts of EpiData Analysis. All users are now encouraged to participate in the testing. A system of comparing estimates, counting with results of Stata or Epi6 is applied. Currently the system contains around 1000 different tests. But maybe the system is not taking care of all problems, therefore user tests are also important. A complete list of changes is shown at http://www.epidata.dk/analysisversioninfo.htm. Main points are: Output is simplified. You only get what you ask for. To get more add options (e.g. /T) to the command Tables Extended (sorting, percentages, weights, outbreak) Metadata commands: missingvalue, labelvalue, rename Outbreak analysis: "tab outcome exposure variables /oa" "epicurve datevar outcome group" The test version is placed at: Http://www.epidata.dk/testing.php Please discuss the new version on this list. If you find definite bugs report to http://www.epidata.dk/php/mantis, where all development is documented. .............................................................. Regarding the discussion last week of differences btw. open-source and free software. As announced earlier a "master plan" for rewriting all EpiData Software to Open-Source as well as platform independence is part of the general development plan for EpiData. Releasing software as open-source makes no sense if the structure and content of the product is not sufficiently modular to allow for several independent development lines. Someone might disagree with me on this, but knowing how fragile software development is and seing the increased requirements for documentation and quality assurance I am assured that a controlled situation is preferable at this point in time. For almost all end users having a stable, quality assured software line is more important than having access to independent and possibly confusing development. But there should be no doubt that the aim is at an appropriate time to release the product source-code as open-source. Should anyone have a lot of energy or time to add to the project there are many issues needing assistance, e.g. answering questions on the epidata-list, assisting in sorting incoming mails to the help line, releasing mails for the epidata-list coming from un-subscribed persons, creating a FAQ collection such as that running for Stata at http://www.stata.com/support/faqs/ or joining a group running a wiki for EpiData, which could contain the FAQ. A start of this can be seen at www.epidata.org/wiki, but will not be announced before such a group has been established (A coordinator has been found). Notice also that for EpiData Entry users can develop their own CHK file commands. Modules for doing so (source code and examples) are found on http://www.epidata.dk/documentation.php ..............................................................

Hello, For French users Je n'ai pas eu beaucoup de chances avec mon precedent mail, proposant une eventuelle mutualisation des personnes pour la realisation de guides d'aide a l'utilisation de EPIDATA. J'ai finalement realise trois guides : - Un 8-pages de prise en main rapide - Un guide pour l'analyse seule - Un guide pour le controle des donnees avec un mot sur les fichiers relationnels Ces trois documents ne peuvent être joints a ce mail (taille bornee). Vous pourrez les trouver sur le site internet du Reseau Securite-Naissance des Pays de la Loire www.reseau-naissance.fr Je reste a votre disposition Bernard Branger branger-bono(a)wanadoo.fr Message redige sans accent

[EpiData-list] Importing other file formats (eg SPSS) to create REC, CHK and QES files
by epidata-list＠lists.umanitoba.ca 23 Jan '07

23 Jan '07

Hello, I know that EpiData has the ability to output data in SPSS format (a TXT file and an SPS file which can be run to create a SAV file) - is it possible to reverse this process and either use a SAV file or a SPS/TXT combination to create REC and CHK files (and ideally even the QES file to go with them)? I'm also interested if I could generate REC/CHK files from other file formats, such as Triple-S (and output to this too) - what options are there currently for doing this. If nothing, are any being worked on or considered for implementation in future versions? I would be interested in helping with developing these things if that is possible or would help also. Thanks, Charity

command labelvalue in analysis

A user wrote: "I discovered this link http://www.epidata.dk/downloads/docs/commands.htm" The link is outdated and has been deleted today. The overview of the latest commands in most recent development versions can always be found at "http://www.epidata.dk/commands.htm" However the release of next version of analysis will not take place until I find it sufficiently stable for general testing and usage. At that point you will find a copy on the testing page: http://www.epidata.dk/testing.php I reject telling when a given release is going to be made - since this is basically unknown. Unfortunately I am somewhat naive in this respect, since severe problems have been showing up during the major rewrite ongoing since release of v1.0 build 68. The list will be informed when the release is ready. The same answer applies to the other question: > When I calculate proportions, how to have Interval of confaince? > In Epiinfo, the command is Freq "Var"/C!! > Speed of development can usually be increased by confirmed donations to the EpiData Association. At this moment the latest donations have been given by the World Lung Foundation and the Swiss MPH education organisation. Thanks for the donations. Regards Jens Lauritsen EpiData Association
