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.
