PyfengForPapers hosts a collection of the Py notebooks (.ipynb) that use PyFENG package to reproduce the results of financial engineering papers. This repository aims to help researchers by providing a replication for published papers. The installation of PyFENG is required.

• For the first-time installation,

  pip install pyfeng

• For an upgrade,

  pip install --upgrade pyfeng

• If running on your modified implementation,
  • Make a local copy of PyFENG repository by forking or download.
  • Make necessary modifications.
  • Uncomment the following lines in the beginning of notebook file. Then, the local PyFENG will be used.
