Major news : Rewritten EpiData Analysis v1.0, updated versions of EpiData Manager and EntryClient

by EpiData development and support

For all EpiData Users. Today we have taken a major step forward with the release of a rewritten EpiData Analysis in version 1.0 and version 4.4 of Manager and EntryClient. The ability to use relational structures, encryption, user logging and other complex aspects has been implemented. We do hope that users will find this an important step forward. It will not be long before further functionality is available in Analysis. In the test versions we have already a functional aggregate, and tables is next step. Get the new versions for Linux, Mac and Windows from: www.epidata.dk/download.php Read the introduction documents for each software from the help menu after you start the software. As always when versions of software change be particularly critical to ensure backup copies of all data in a secure place before updating. Analysis is ready as v1.0 in terms of: - read project files (epx/epz including encrypted files), but also Stata dta, CSV, Rec+Chk files) - data management - combine files (merge, append) - saving, exporting and archiving data files (epx, dta, csv, ddi-3.1) including metadata - frequencies, count, means - validation of files and other aspects For Windows there is a combined installer for all three types of software - regardless of whether you have a 32 or 64 bit computer. All three EpiData software tools use an updated data file structure. Once you have read and saved an epx file it will not be possible to open it in a previous version of the software. So make sure to update all copies of the software that you are using, e.g. if you have local data entry. All example files are now located in a specific user specified folder, which you may choose during installation. In that folder example pgm files for analysis and pdf introduction documents are contained. Observation: on some restricted systems (eg. in a hospital) the user might not be asked to decide the folder position during installation or other user specifications. We cannot apparently control the installation completely. As always discuss function on this list and contact us in case of serious or reproducible data errors occurring due to system functioning on info (at) epidata.dk We wish to express as well thanks for inspiration and help from in particular Jamie Hockin and Hans Rieder, but also received funding from The Union (DFID fund) and other funding bodies.

new ANALYSIS (with tables and aggregate) available

by EpiData development and support

For all users Today we uploaded a revised (new) Analysis v1.2.0.0, which can create tables and do aggregation of data. Get the new versions from : http://www.epidata.dk/download.php On that page you may always see a complete list of changes with versions. The table module in (new) EpiData Analysis will now do proper row, column and total percentages, and the aggregate command may create tables of estimates (mean, Ci, percentiles) for all combinations defined by subgroups of other variables. You may also save the aggregate table as a separate dataset within the project. In the help file of (new) Analysis the header indicates that for doing: Graphs, SPC graphs, Kaplan-Meier lifetables and testing other than basic Chi2 you must still use EpiData Analysis Classic. We identified a few peculiar bugs related to combinations of missing data or specifications when reading rec files and saving Stata files (beyond version 13) . Since reading and writing of data files is a common core function shared between Manager, EntryClient and Analysis we have also uploaded rebuild versions of these. Please comment use and problems on this list. Jens Lauritsen and Torsten B. Christiansen EpiData Association Denmark

Re: [EpiData-list] A request for download page of previous versions

by EpiData development and support

A direct mail was sent regarding previous versions: Always use the latest public version. Test and experimental versions should never be used for "real" project data, but should be tested on copies of data. When bugs and errors are found we fix these and sometimes this may change the structure of the epx/epz project file. New public release versions can always read previous forms. If you find an error with a new version, please report the error, such that we can locate the problem and fix it.
