Is there any way to import from Excel to EpiData?

Hello everyone. I understand from the user manuals that data can be imported from text, dbase, and STATA. Has anyone figured out a way to import an Excel database, even though technically it is not an option? Thank you Todd Services Technique d'Appui aux Opérations (STAO) Médecins du Monde - France 62 rue Marcadet 75018 Paris - France Tél: +33 (0)1 44 92 16 18

Anyone working on EpiData in Johannesburg
by epidata-list＠lists.umanitoba.ca 22 Apr '07

Hi, I wrote introductory guideline for EpiData at Karolinska Institute, Stockholm. Now I am in Johannesburg for data collection, will spend around 10 months here. People working in bioinformatics are interested in learning more about EpiData and was asked to present about database. Anyone living in Johannesburg and interested in joining to teach EpiData?

Until now the statistics have NOT been adapted to other confidence intervals than 95%. For a given table it should be quite easy though given you have the raw numbers. Enter these into e.g. www.openepi.com and get the desired 90% CI. For analysis the possibility of users defining CI (e.g. 90 95 99) could be implemented within the next few years. Just now for the v2 of EpiData Analysis we are working on some "subtle" internal issues, which is why seemingly very little progress was made recently. The implementation of the Upper Case fields <AAAAA> revealed need for quite many changes, since all internal parts were made only for uppercase handling. The problems mentioned in the Mantis database and on the www.epidata.dk/testing.php page that the latest test build does not save data properly has been solved.

Confidence intervals and stats
by epidata-list＠lists.umanitoba.ca 19 Apr '07

19 Apr '07

Hi again I sent a request on the this earlier but I don't know if everyone was on holiday because I didn't get any response:-)! So I am trying again! I would like to know how one could change the confidence Interval (CI) to reflect 90% instead of 95% which I assume is the default. I am working in Epidata Analysis V2.0 (build 108). If one uses the command: Set TABLE CI HEADER="(90% CI)", it does change the header to reflect 90% but the actual CI values still stays the same. I also need to get the Fischer Exact p value, as well as the CI values as part of my table output. I looked in the help function and the command options do not seem to match up with the explanations. There is supposed to be an option that says 'add an extra table with a summary of chi square, p values etc' but I can't find the appropriate command on the LHS. I have been able to get the Fischer's exact p by using the command /EX but the command /CI didn't give me any confidence intervals. Please let me know if there is a flaw in my logic as I am not a stats expert. Thanks.

Re: common site for teaching/training materials
by epidata-list＠lists.umanitoba.ca 19 Apr '07

19 Apr '07

AS some of you might have noticed I have already defined an open EpiData site - in the form of a wiki - where some experiences on using this technology already exist. The www.epidata.org site has been reserved by me a few years back with the intention that this could serve as the "community" site for EpiData, maintained collectively by the body of epidata users. Pedro Arias and I created teaching material for use in the Canadian Field Epi course last autumn. Off list I have suggested to a number of users mentioning materials to add these to the site, but the time and energy to get onto a new way of working can be difficult to find for already busy people. If the material already exist it is quite easy to copy and paste into the wiki and upload the figures/images. The experimental site is found at http://www.epidata.org/wiki There is some learning problems in the beginning when editing in the wiki format, but with a few experiments it works very well. An introduction is shown at http://en.wikipedia.org/wiki/Wikipedia:How_to_edit_a_page The optimal would be that a group of persons together take on the responsibility of maintaining the open site, since we must unfortunately expect that someone will add irrelevant material or suggestions which otherwise are not appropriate. The initial steps of forming such a group has been made, but awaits further initiatives.

Thanks for the link. I was interested to see the Epidata training materials on this site and also the ones now on the Epidata website. I'd be very interested in any other links. I'm especially interested in materials that deal with outbreaks so it was great to see the case study about Tiramisu on the epidata website - but that only deals with the analysis side. (Here we use Epidata for our questionnaires and data entry but use Epi Info for analysis). I've done a training manual for our public health staff about using Epidata and have an outbreak case study exercise that uses epidata and epi info, but have not made on line versions yet. I would be interested in talking to others - perhaps off line about materials they use for epidata training. thanks again Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 13/04/2007 5:26 p.m. >>> Have a look at the many available documentations on the web.

BMI from US measures
by epidata-list＠lists.umanitoba.ca 13 Apr '07

13 Apr '07

If you do not wish to show conversion of US measures into SI units in the QES file, then your QES file should have this: *.QES file wtpd Weight in US pounds ###.# htft Height in US feet # htin Height in US inches ## bmi Body Mass Index in kg/m^2 ##.# You then make all your calculations in the CHK file to get the BMI in SI units: *.CHK file * Definitions from Wikipedia * 1 US foot=(1200/3937) meters * 1 US inch=25.4 millimeters * 1 US pound= 453.59237 grams wtpd MUSTENTER END htft MUSTENTER END htin MUSTENTER AFTER ENTRY bmi=(wtpd*0.45359237)/((htft*(1200/3937)+(htin*0.0254))^2) END END bmi NOENTER END and that should do it. Beware of empty fields contributing to the denominator. Should that be the case, you must make provisions in the CHK file. The above works only if there are no zeros for the two denominator variables, and not permitting any blank fields.
