In this paper, we show how to combine Kalman filter and stochastic models to forecast two key financial variables: stochastic volatility and price… In both cases, our purpose is to separate the true price movement from noise caused by the influence of minor factors that have a short-term effect on the price. Our task is to determine the main trends based on these short and long movements. In this article, I will use ARIMA model to forecast exchange rates. As such, we will model our price predictions as log-linear with respect to seat quality. April 19, 2017 Kalman Filters is ideal for systems which are continuously changing and well suited for building real time systems as kalman filter is a dynamic linear model, that is able to adapt to an ever changing environment. }
