RE: [EpiData-list] How should EpiData Analysis read a CSV (CommaSeparated File)

RE: [EpiData-list] second try: order of missing valuesindocument->codebook

by epidata-list＠lists.umanitoba.ca

I gave it a try: - When the variable is NUMERIC (as it is the case in your file), missing (.) values appear at the end of the tabulation. When it is STRING, missing (.) values appear at the top of the tabulation as follows: var1S -------------------------------------------------------------------- var1S type: Texte majuscule Libellés des codes: libellé_var1s manquant: 3/7 valeurs uniques: 4 tabulation: Freq. P.100 Valeur Libellé 3 42.9 . 1 14.3 1 1 1 14.3 2 2 2 28.6 3 3 var2N -------------------------------------------------------------------- var2N type: Numérique Libellés des codes: libellé_var1s manquant: 3/7 fourchette: [2 ; 3] valeurs uniques: 3 tabulation: Freq. P.100 Valeur Libellé 3 42.9 2 2 1 14.3 3 3 3 42.9 . Note: as shown in your example, there is a redundancy in the checkblock: the variable is controlled by a list if valid values ('label_ramde7'), AND there a Range command (0-10,98). As it is already controlled by the list, it is not useful to control it twice with 'Range - legal'. Choose either of the 2 control systems, remove the other one, and check again. ______________________________________________ Gilles DELMAS Institut de Veille Sanitaire Dept.

re: variable names

by epidata-list＠lists.umanitoba.ca

You can change this by selecting the option to use the first word as the field name (under File, Options, Create data file tab). This is described in the help files. You may have to reset your options when you install a new version. There is a newer version on epidata.dk now (12 March 2006) Jamie ============================= In the latest version of Epidata (12012006) field names is not functioning well. I choose field names to be the first word in the line and the software assigne the name with 10 first characters in the line. I can change field names but it is a lot of work. Is it any other solution? Luciana Petrucci Gigante

First word versus first 10 characters for field naming in EpiData Entry v3.1 (12012006)

by epidata-list＠lists.umanitoba.ca

We are looking into this problem, which is an error in the installation routine NOT in the actual software once installed. To get the correct behaviour you desire do this: 1. Start epidata.exe 2. Go into the options (see file menu) 3. Choose the "Create data file" part 4. Select either "first word" or "automatic" as you please. The issue in relation to installation will be solved, but until so do as shown in point 1-4. Regards Jens Lauritsen EpiData Association

RE: Design decision.... Restricted words

by epidata-list＠lists.umanitoba.ca

> Should we : > a. Adopt a strategy, where users are warned when creating files where > field names/variables are > given the same names as a restricted word - a warning. > > b. Maintain current where users will find out since either an error or > occur or nothing happens when > they create confusion in this way - a "non-friendly" way towards > users. > > c. A strategy where field names cannot have the same names as functions. > - a restrictive strategy. Hi, I don't fully understand what option a) implies. If an user receives a warning, can (s)he continues working?. And what next?. Will (s)he get an error sometimes?. In my opinion if there is a risk of conflict bettwen a command or funtion name and the name of a field or variable this name should be prohibited. So, i think the most restrictive option should be implemented (whith a very clear message saying "the word XXXXX is a reserved word, choose another for your variable name").
