Draco

Draco

Draco provides a simple interface for accessing many tools common to econometric analysis. Specifically, it is an open source pure-Java econometrics package for performing statistical analyses in a simple, sensible approach.

Draco provides many data manipulation and statistical analysis tools available in expensive commercial software.

Draco provides a familiar, yet powerful and intuitive, user interface to improve efficiency. The user interface of Draco is reminiscent to spreadsheet applications, presenting all data to the user for all stored variables. Approximatrix provides limited support for free users of the software, but there is also commercial support available.
