New test version of Manager and Analysis
by epidata-list＠lists.umanitoba.ca 03 Sep '11

03 Sep '11

The release of September 2nd is a minor update for Manager and EpiData Analysis, in which a few bug have been found and fixed. Manager: * Fixed bug where exporting to STATA did not export valuelabels. * Added support for importing .rec files with password protection. * Fixed minor bug where importing .rec files with valuelabels under special circumstances were not imported correctly. * Fixed significant bug in importing structure of STATA files could render computer useless (HUGE memory usage). * Fixed significant bug where deleting a section, with fields/heading moved out of could also delete the fields/headings. * Added "space extender". A heading is placed a "page" down on the designer, to extend the working area for placing fields, sections and headings. Analysis: * Fixed a bug where importing project files .epx/.epz would create a buggy .chk file on saving data from within Analysis. ==================================== Regards Torsten Christiansen and Jens Lauritsen EpiData Association

We can use the following for the conditional value label look-up, disease AFTER ENTRY IF (disease='A') THEN GOTO subtypeA EXIT ENDIF IF (disease='B') THEN GOTO subtypeB ENDIF END END subtypeA COMMENT LEGAL USE label_subtypea SHOW TYPE COMMENT END subtypeB COMMENT LEGAL USE label_subtypeb SHOW TYPE COMMENT END Bijay Adhikari On Fri, Sep 2, 2011 at 11:00 AM, <epidata-list-request(a)lists.umanitoba.ca>wrote: > Send EpiData-list mailing list submissions to > epidata-list(a)lists.umanitoba.ca > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.umanitoba.ca/mailman/listinfo/epidata-list > or, via email, send a message with subject or body 'help' to > epidata-list-request(a)lists.umanitoba.ca > > You can reach the person managing the list at > epidata-list-owner(a)lists.umanitoba.ca > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of EpiData-list digest..." > > > EpiData-list mailing list > ___________________________________ > > Today's Topics: > > 1.

Greetings. Is there a way to do a conditional value label look up in either the current or in the new test version of EpiData? For instance, if field disease equals A then field subtype has values 1,2,3 for selection, if field disease equals B then field subtype has values 4,5,6, etc. Thank-you, and well done to the development team for excellent progress. _______________________________________ Stephen Drew Health Data Analyst Region of Waterloo Public Health Waterloo, ON ======================================================================== Thanks Stephen, what about using the expression if: Example for disease A disease_A BEFORE ENTRY IF disease_A = 1 or "AFP" THEN Symptom = 1 GOTO admission ENDIF END END Next thing to be done is the following expression IF disease_B = 2 or "Yellow_Fever" THEN Symptom = 3 GOTO admission_tropic (i.e another subtype) ENDIF END END As you can see this can be very time consuming, however it could best done at the data management stage where you could create or generate new variable appropriately before cracking on with the analysis. However, if you really want to proceed with: "A then field subtype has values 1,2,3 for selection" then the other thing that you could do would be to assign a unique code; such as if field subtype has values 1,2,3, then coded it 1, for value 4-7 coded it 2; this will make it easy. I am struggling to understand why you need values 1, 2, 3 in the same field at the same time?

Greetings. Is there a way to do a conditional value label look up in either the current or in the new test version of EpiData? For instance, if field disease equals A then field subtype has values 1,2,3 for selection, if field disease equals B then field subtype has values 4,5,6, etc. Thank-you, and well done to the development team for excellent progress. _______________________________________ Stephen Drew Health Data Analyst Region of Waterloo Public Health Waterloo, ON
