was specially created to assist researchers to carry out epidemiological investigations.
It has functions which carry the following tasks:
functions that are used to create questionnaires, edit files that contain
data-checking and data-coding rules, and write and edit text (such as the output from
EpiData’s data documentation functions).
functions that allow you to make data files from questionnaire files,
enter, edit, and query data.
functions that allow you to add range checking, skip patterns,
legal values, and complex coding rules to data as it is entered ( checking).
functions that allow you to apply range checking, skip patterns,
legal values, and complex coding rules to data it has been entered (
functions that compare two files and report any differences
between them ().
functions that allow you to create new variables or
manipulate existing variables (e.g. calculation of latency periods, grouping ages etc.).
function that allows you to import data from text, dBase, and STATA
An function that allows you to export data to text, dBase, STATA, Excel,
SAS, and SPSS format files for subsequent analysis.
functions to append (i.e. join end-to-end), merge (i.e. join
side-to-side), or restructure data files.
functions that list data, describe file structures and data
checking rules applied to files, produce frequency tables and descriptive statistics for
variables in a file, and count records in one or more files using values entered into
functions that allow you to pack (i.e. remove deleted records) data files,
compress data files, make backup copies of data files and associated questionnaires and
data checking rules, copy file structures, create questionnaires from existing data files,
and rename fields in a file.
does not contain any complex data analysis functions but data may be exported to a
variety of common formats. use the same file format as EpiInfo version 6.xx (a
popular MSDOS-based program widely used by field epidemiologists). Any program that can
read EpiInfo version 6.xx data (.REC) files may also be used to analyse data entered using
. Available tools include the , , and modules of EpiInfo
version 6.xx, the module of EpiInfo 2000, EpiMap version 2, and numerous add-in
programs that perform logistic regression, conditional logistic regression, and survival analysis.
Basic data analysis functions may be added to subsequent versions of .
