Forecasting

3050
This Forecasting library has a couple of Novel and traditional approaches to forecasting stock prices.
Traditionally, it provides a basic ARIMA forecaster using simple autoregression, as well as a linear regression and quadratic regression channel forecaster.

Novel approaches to forecasting include:

1) A Moving Average based Forecaster (modelled after ARIMA), it is capable of forecasting based on a user selected SMA.

2) Z-Score Forecast: Forecasting based on Z-Score (example displayed in chart).
