WebARCH/GARCH models are an alterative model which allow for parameters to be estimated in a likelihood-based model. The basic driver of the model is a weighted average of past squared residuals. These lagged squared residuals are known as ARCH terms. Webarch is Python 3 only. Version 4.8 is the final version that supported Python 2.7.
