For the purposes of this exercise, it was the perfect tool for exploration. Time series analysis is a complex subject but, in short, when we use our usual cross-sectional techniques such as regression on time series data, variables can appear "more significant" than they really are and we are not taking advantage of the information the serial correlation in the data provides. Introducing Tensorflow; Introducing Tensorflow; Why Tensorflow? What is tensorflow?Deep learning with Tensorflow in R 1. Hyndsight. Let’s calculate some performance measures such as the RMSE and MAPE for the ARIMA model. Test the hypothesis that the ARIMA based forecast is more accurate than the linear model based forecast.
