EpiData was specially created to assist researchers to carry out epidemiological investigations. It has functions which carry the following tasks:
- Text Editor functions that are used to create questionnaires, edit files that contain data-checking and data-coding rules, and write and edit text.
- Data Entry functions that allow you to make data files from questionnaire files, enter, edit, and query data.
- Data Checking functions that allow you to add range checking, skip patterns, legal values, and complex coding rules to data as it is entered. [interactive checking, batch checking and validation]
- Coding and Calculation functions that allow you to create new variables or manipulate existing variables (e.g. calculation of latency periods, grouping ages etc.).
- Import function that allows you to import data from text, dBase, and STATA files
- Export function that allows you to export data to text, dBase, STATA, Excel, SAS, and SPSS format files for subsequent analysis.
- Data Management functions to append (i.e. join end-to-end), merge (i.e. join side-to-side), or restructure data files.
- Documentation 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 particular variables.
- Utility 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.
EpiData does not contain any complex data analysis functions but data may be exported to a variety of common formats.
