You do not use the JUMP command, but rather use the logic you show in your message. Use the Edit button in the Check screen and type in the if statement. You have access to many useful functions as well - in this case the ABSolute value function. There are good examples in the help file accessible from within EpiData.

How to insert calculation in JUMP add/revise check
by epidata-list＠lists.umanitoba.ca 15 Mar '05

15 Mar '05

I am a new EpiData user. I am creating a data entry screen for anthropometric data. There are two weight measurements - and a third if the first two differ by +/- 0.5 kg. How can I incorporate this calculation in the JUMP section of the Add/Revise Checks so (1) if WT1 - WT2 GE 0.5 OR LE -0.5 go to WT3 (2) else go to HT1 [the next field] Thank you.

Re:Search problem

Could the problem be that the search is just marked as say 'forward' and you are sometimes already past the record you search for? Then marked 'search all records' instead or go to record 1 first.

"find records" not working properly
by epidata-list＠lists.umanitoba.ca 14 Mar '05

14 Mar '05

Hi all, I'm a new user of EpiData, and have a question regarding "finding records." When I try to find a certain case using a "Find Records" command, I sometimes get an error message saying "searching string(s) not found," even though the record I'm looking for is in the file. The identifier field I used is a numeric variable (caseid with four digits). Even more perplexing is for other data files, the "Find Records" works. I've created all data files in a same way, and don't understand why "Find Records" works sometimes, but not other times. Am I missing something or doing in a wrong way? I have a same problem with both EpiData 2.01 and 3.02 versions. Any helps or comments on this will be greatly appreciated. Best, Jin

autosearch and document
by epidata-list＠lists.umanitoba.ca 09 Mar '05

09 Mar '05

Dear Dr. Lauritsen, When I used "autosearch" command in the check file in order to prevent creation of duplicate records, I found that the "type comment on" command in the same field became disabled, and the double entry verfication is also disabled. Why ? And How to solve it? Sometimes in "View Data", "List Data" and "Codebook", the values of numeric fields were disappeard. I don't know why and have not discoverd any regluar rule. Thank you very much. Best Regards, Yali Zhang _________________________________________________________________ 免费下载 MSN Explorer: http://explorer.msn.com/lccn

automatic date
by epidata-list＠lists.umanitoba.ca 07 Mar '05

07 Mar '05

Has anyone noticed the following with the automatic date field type <Today-dmy>? When entering the first record for the day, this field does not display today's date but displays the date when the last record was entered. Once a record has been entered and saved, this field is updated to the current date. When entering a new record I expected the automatic date to display today's date regardless of whether or not a record has been entered today. Do you have any idea why this is not the case?

Initial test of Analysis build 18 - TABLES
by epidata-list＠lists.umanitoba.ca 04 Mar '05

04 Mar '05

As I noticed the table was not implemented correctly in build 18, but should be correct (for the data I tested) in build 19. Build 19 was made available early today/late last night depending on where you live. The intention was to always have as pointed out by Jamie Hockin: TABLES outcomevar exposurevar stratifyvar1 stratifyvar2 stratifyvar3 Please review the adapted commands and functions list. You can search on (ctrl+f) "table epi" and in options for search mark out "helpfie" and the file will open in the output window. (the file has a formatting error now - but contents are there) set table labels=on[off] (Use comment legal "value labels" as text descriptors in tables) set table values=on[off] (show category values in tables) set table epi=on[off] (With on: tables are inverted (highest values in top left corner) set table percents=on[off] set table percents format="P1()"[off] (Content percents coloumn) 1: decimals () before after. e.g. "P2 %" set table percents header="%" (Contents of column header for percents) set table RR=on[off] show Risk Ratio in 2x2 tables set table OR=on[off] show Odds Ratios in 2x2 tables to control statistics output: set table statistics="OR RR EXACT CHI" eliminate the ones you do not want. e.g. set table statistics="CHI" regards Jens Lauritsen EpiData Association
