pmdarima: ARIMA estimators for Python

pmdarima brings R’s beloved auto.arima to Python, making an even stronger case for why you don’t need R for data science. pmdarima is 100% Python + Cython and does not leverage any R code, but is implemented in a powerful, yet easy-to-use set of functions & classes that will be familiar to scikit-learn users.
