PAIDA is pure Python scientific analysis package.
The main features are:
  • Pure Python!
    • Jython (Python in Java) OK!
  • AIDA (Abstract Interfaces for Data Analysis) support
  • Creating/Plotting the histogram, ntuple, profile and cloud
  • Parameter optimization (Fitting)
    • you can constrain and/or fix parameters
    • parabolic and asymmetric error evaluation
    • various fitting methods are supported
      • including GA (Genetic Algorithm)
  • XML based storing
  • Matrix calculation

AIDA has already both C++ and Java implementations. Many analysis systems such as GEANT4, JAS3, OpenScientist, and Anaphe use AIDA.
