Last Updated on August 28, 2019 Making out-of-sample forecasts can be confusing when getting started with time series data. The statsmodels Python API provides functions for performing one-step and multi-step out-of-sample forecasts. In this tutorial, you will clear up any confusion you have about making out-of-sample forecasts with time series data in Python. After completing this tutorial, you will know: How to make a one-step out-of-sample forecast. How to make a multi-step out-of-sample forecast. The difference between the forecast() and […]

Last Updated on August 28, 2019 How much history is required for a time series forecast model? This is a problem-specific question that we can investigate by designing an experiment. In this tutorial, you will discover the effect that history size has on the skill of an ARIMA forecast model in Python. Specifically, in this tutorial, you will: Load a standard dataset and fit an ARIMA model. Design and execute a sensitivity analysis of the number of years of historic […]

Last Updated on September 16, 2020 The use of machine learning methods on time series data requires feature engineering. A univariate time series dataset is only comprised of a sequence of observations. These must be transformed into input and output features in order to use supervised learning algorithms. The problem is that there is little limit to the type and number of features you can engineer for a time series problem. Classical time series analysis tools like the correlogram can […]

Last Updated on August 28, 2019 It is important to establish a strong baseline of performance on a time series forecasting problem and to not fool yourself into thinking that sophisticated methods are skillful, when in fact they are not. This requires that you evaluate a suite of standard naive, or simple, time series forecasting models to get an idea of the worst acceptable performance on the problem for more sophisticated models to beat. Applying these simple models can also […]

Last Updated on August 21, 2019 There are many parameters to consider when configuring an ARIMA model with Statsmodels in Python. In this tutorial, we take a look at a few key parameters (other than the order parameter) that you may be curious about. Specifically, after completing this tutorial, you will know: How to suppress noisy output from the underlying mathematical libraries when fitting an ARIMA model. The effect of enabling or disabling a trend term in your ARIMA model. […]
