pyEDM 2.1.0

Python/Pandas toolset for Empirical Dynamic Modeling.

Empirical Dynamic Modeling (EDM)

---

This package provides a Python/Pandas DataFrame toolset for EDM analysis. Introduction and documentation are are avilable online, or in the package API docs. A Jupyter notebook interface is available at jpyEDM.

Functionality includes:

• Simplex projection (Sugihara and May 1990)
• Sequential Locally Weighted Global Linear Maps (S-Map) (Sugihara 1994)
• Multivariate embeddings (Dixon et. al. 1999)
• Convergent cross mapping (Sugihara et. al. 2012)
• Multiview embedding (Ye and Sugihara 2016)

Installation

Python Package Index (PyPI)

Certain MacOS, Linux and Windows platforms are supported with prebuilt binary distributions hosted on PyPI pyEDM and can be installed with the Python pip module: python -m pip install pyEDM

---

Usage

Examples can be executed in the python command line:

>>> import pyEDM
>>> pyEDM.Examples()
