Dear list, I have two questions regarding Jumps in EpiData Entry. 1) I want to jump to variable v10 if de score for v8 is 1 to 7. Of course this works: v8 RANGE 1 9 COMMENT LEGAL USE oplcat JUMPS 1 v10 2 v10 3 v10 4 v10 5 v10 6 v10 7 v10 END MUSTENTER END Is a shorter syntax possible and if so, how? 2) Is it possible to make a jump defination that depends on the value entered in a previous question? For example: After entering the value for variable v5 I want to jump to v8 if the answer on question v3=1. Kind Regards, Pieter van Groenestijn The Netherlands

fill fields from COMMENT LEGAL file

I'm studying the copydata example to learn how to extract several variables from a file identified in a COMMENT LEGAL statement. In A3.chk, the statement "TYPE COMMENT atransfer" appears. What is atransfer? I don't see where it has been defined as a variable and I don't find it as a system variable. Further, the program seems to be parsing the string in atransfer according to the position of punctuation. Where is the format of this string defined? Perhaps to be a bit more explicit: I have file with a list of CHWs: District, Village, CHW name and a survey conducted by the CHWs. As the data is entered for the survey, I'd like to present pick lists to facilitate entry. The data is quite strictly hierarchical: Villages occur within Districts, an CHWs live in villages. Thank you,

Command Select

Thank you for your response. Example with my own file. .freq castem; castem ----------- N ----------- 1 153 2 150 3 632 ----------- Total 935 ----------- .select castem<>3 do; Selecting, please wait... (303 of 935 selected) .begin; ==> No operative (idem begin without < ; >) ERROR: Line 1: Syntax error at pos 7: ERROR: Unexpected end of line! Perhaps a ";" is missing? .freq castem; ==> no selection... castem ----------- N ----------- 1 153 2 150 3 632 ----------- Total 935 ----------- .select castem=1 do drop data; ==> objective : keep codage 1 Selecting, please wait... (153 of 935 selected) (153 observations dropped) .freq castem; ==> Selection code<> 1 (link avec drop data ?) castem ----------- N ----------- 2 150 3 632 ----------- Total 782 ----------- And an another (and last) question : how to delete the current selection? Thank you. Bernard Branger, Nantes, France

New analysis
by EpiData development and support 06 Feb '21

06 Feb '21

Hello, For training, I'm trying to understand the new version of "Analysis". A few comments : - The command "freq var ! r;" (as shown in the guide) doesn't work, but "freq var ! pr" is OK. Strictly speaking and on the educational plan, the percentages presented with "freq" are in columns : "freq var ! c;" or "freq var ! pc;" would be more logical. - To select a part of the file, I noted, (as an example for a frequency) the command "select (var1 <3) do freq var2 ! pr;". Should we repeat with each command "select (var1 <3) do"? Is there a way, like the old "select", to select part of the file for further commands? - The command (example) "select (var1 = 3) do var1: = 2;" is quite complicated compared to that "if ... then ...." - How to create a new numeric variable with 3 digits and 2 decimal places? As in the old "define var ###. ##"? - When will the "regress" commands and the graph commands (including scatter with a regression line as in the old "Epi-Info" ...? Thank you for your help.
