MISSINGVALUE / JUMPS RESET commands
by epidata-list＠lists.umanitoba.ca 08 Dec '04

08 Dec '04

Hello, I've really enjoyed using EpiData, and I have to say that the application I am creating will be a HUGE improvement over what our data collectors had been using. They're excited to start using EpiData. I am having problems using some check file commands, however. When I use the command "Jumps Reset 99", this code mysteriously disappears from my .chk file without warning after I save and exit. If I use "Jumps Reset 9", it stays. I need to use 99, though, because 9 is a valid code for some of my variables. I am also having trouble using the Missingvalue command. When I type in "MISSINGVALUE 98" in a field, this code will also mysteriously disappear from my .chk file, though not always immediately, like "Jumps Reset 99" does. I have tried using the missingvalue command in the before file block, but I've had no luck with this. I am wondering if the size of my .chk file has anything to do with these problems. I saw in the help file that there is a limit of 64Kb if you work in the editor, but I use the add / revise checks feature so I'm not sure if this affects me. My .chk file is 90Kb, and over 4200 lines long. If I can't use Jumps Reset 99, this will increase the size of my .chk file even further. Besides the above problems, everything is working OK. Any advice that you can give would be greatly appreciated. Thank you, Katie Thornton Programmer Institute for Research on Poverty

Labels in stata after export from epidata
by epidata-list＠lists.umanitoba.ca 07 Dec '04

Correct. Thanks! However, in order for the value label to work properly in Stata, it seems that the value label must be written in ascending order, i.e. 0 No_Adjuv 1 Adjuv not the other way around.

Most likely the problem is a Stata matter of how labels are shown in the data browser Try in stata: use xxxxxxxx (your file) d * check the formats * set format for the variable with problems : format %9.0g x (assume name is x) browse Works here for me. If the display format is too narrow for a given variable, then the label is not showing correctly in browse, but does show correctly at : label list or tab or freq of that variable. If you still have problems send the rec+chk file as an attachment to info(a)epidata.dk or indicate adress for download. regards -- Jens Lauritsen Coordinator and initiator of EpiData Project http://www.epidata.dk

Problems with variable labels after transferring data from Epidata to Stata
by epidata-list＠lists.umanitoba.ca 06 Dec '04

06 Dec '04

Hi: I'm a newcomer to Epidata and am holding a course on Data entry and analysis for our Masters students this week. I have a problem in that variable labels that seem to work well in Epidata 3.02 are not maintained properly after exporting the data to Stata. It works fine when exporting to SPSS. The pictures under http://www.cih.uib.no/presentations/hsommerfelt/EpidataLabels.JPG illustrate the problem. I would greatly appreciate advice on how to solve the problem. Yours sincerely Professor Halvor Sommerfelt, MD, PhD, DTM, Centre for International Health, University of Bergen, Armauer Hansen Building, N-5021 Bergen, Norway Ph: +47 5597 4987 Fax: +47 5597 4979 http://www.cih.uib.no

RE: STATA labels

Jens Thanks what you advise does fix the problem. However even if the uncompressed STATA file is used and Epidata wants 1.000 in stead of 1, 1.000 is stillnot recognised as a legal value, if you put in 1.000 it says illegal entry. However the whole problem is circumvented when compressing the file as you suggest.

Importing from Stata - problems with labels and comment legal
by epidata-list＠lists.umanitoba.ca 30 Nov '04

30 Nov '04

The reason for problems of importing Stata files with defined value labels can be that in Stata one can attach a label like: 1 female 2 male to a real variable. e.g. #.#### But in EpiData this would mean that the legal value should be: 1.0000 female 2.0000 male So to avoid this before saving the data file in Stata do this: a. read the file (use yourfile) b. compact the file (compress) c. save the file (save newfile) Then you can import the file into epidata and use the labels as defined with 1 for female and 2 for male. Alternatively you can import the first file into EpiData and then make a qes file from the recfile and remove the decimals from that variable. regards Jens Lauritsen The EpiData Association, (EpiData Foreningen)

Svar: [EpiData-list] STATA import

If there is a problem in this respect, please send a copy of that Stata file to info(a)epidata.dk and Just include a few cases, e.g. 5 That is in Stata: use xxxxx keep in 1/5 save epidataexport And then send the epidataexport.dta file as an attachment to me. All defined labels in Stata that I have tested are appropriately used in EpiData and vica versa. The only problem I have recently encountered was that EpiC renamed the names of the labels to epd1 epd2 etc, such that when exporting several files from epidata to stata format and doing a merge in stata there were problems with the labels. That error will be fixed in epic. regards Jens Lauritsen info(a)epidata.dk Initiator and Coordinator for EpiData >>> <epidata-list(a)lists.umanitoba.ca> 29-11-04 8:32 >>> dear Epidata when importing a STATA file into Epidata the value labels are incorporated into the check file but the values are not set as legal values, so even if you enter what F9 suggests you should, epidata keeps saying illegal entry. So this is a problem when a STATA file with value labels is imported. Simple to fix (just put in legal value sin the check file)but not if you have a large file with many variables. Any advice?
