How to calculate in epidataanalysis
by epidata-list＠lists.umanitoba.ca 28 Sep '06

28 Sep '06

To the list: I do have a database with the fields weight (floating number) and height (floating number). I can make operations like defining a new floating variable and using the command newvariable = height/2 or newvariable = height*height but when I tri to define IMC ## and then IMC=weight/(height^2) or IMC=weight/(height*height) I do receive a "data tipe mismatch" as an answer. I cant have an answer when I try to get age as agemonths=(visitdate-birthdate)/30 The same calculations work with epiinfo for dos with the same datafile. Gerson Zanetta de Lima Brazil

EPIDATA really appropriate??
by epidata-list＠lists.umanitoba.ca 25 Sep '06

QUESTION: I may be addressing a biased audiance, but Id like some reassurance that EpiData is the best way to go for capturing questionnaire data, which will then be transferred to STATA. I had started an EpiInfo database but then realized that it does not support double data entry...or at least not very easily. Thanks!!

Query regarding grids??

Question: EpiData does not seem to have the 'Grid' option (To Deal With Repeating Data Within A Questionnaire such as age of household members). Is this true?? Cheers Todd

I really like epidata for data entry. In our public health service we use epidata for data entry and epi info for analysis. We mainly use epidata/epi info for investigating outbreaks. As outbreaks don't come along all the time the computer support software has to be simple so staff can quickly remember how to use it. I teach courses on using epidata and epi info to staff and they find epidata in particular, very easy to learn. The two other things I like about epidata that have stopped me making the switch to doing everything in epi info are 1. How easy it is to have a 'master' qes form in Epiidata. You can open it up - add or delete a few extra questions - save it as a new name and then have a new rec file 2. The way it is easy to add new questions once you have started data entry With outbreaks we usually want to create questionnaires very fast - so being able to quickly adapt existing forms and adapt them once you've started is great. I don't find that Epi info has that flexibility for data entry but I do like it for analysis. I expect Stata can do more things but Epi Info seems to do all we need and of course is free!

Thanks for the suggestion. Even if I have full administator rights for my laptop I did think about that possibility and had already been in touch with our IT people but they could not work it out.

RE: EpiData-list Digest, Vol 35, Issue 1

Hello, I have three questions : - When will the command "combine" be operating in Epidata Analysis ? - The second variable (qualitative in statistics) for the command "means" ("sexe" in the command "means age sexe") must be, in theory, string and created, in Epidata Entry, by "variable _". When it will be possible instead necessity of numeric variable ? - The command "update" and the screen with data tables cannot modify data : on the screen, the data are changed and not in the file... Why ? Thank you Bernard Branger, Nantes, France

replicate datafile structure, without the data
by epidata-list＠lists.umanitoba.ca 07 Sep '06

07 Sep '06

I will be conducting a survey study very similar to one I've done before. I want to use the same datafile structure: the questions, datatypes, and checks will be nearly identical. Is there an easy way to produce a new set of .rec, .qes, and .chk files, replicas of the old ones, but with no records? Then I can make some small modifications before entering the new data. I'd hate to half to do it all again from scratch. Thanks. --Chris -- Christopher W.
