White Noise Time Series with Python

White Noise Time Series with Python

White noise is an important concept in time series forecasting. If a time series is white noise, it is a sequence of random numbers and cannot be predicted. If the series of forecast errors are not white noise, it suggests improvements could be made to the predictive model. In this tutorial, you will discover white […]

Understand Time Series Forecast Uncertainty Using Confidence Intervals with Python

Understand Time Series Forecast Uncertainty Using Prediction Intervals with Python

Time series forecast models can both make predictions and provide a prediction interval for those predictions. Prediction intervals provide an upper and lower expectation for the real observation. These can be useful for assessing the range of real possible outcomes for a prediction and for better understanding the skill of the model In this tutorial, […]

Autocorrelation Plot of the Minimum Daily Temperatures Dataset

A Gentle Introduction to Autocorrelation and Partial Autocorrelation

Autocorrelation and partial autocorrelation plots are heavily used in time series analysis and forecasting. These are plots that graphically summarize the strength of a relationship with an observation in a time series with observations at prior time steps. The difference between autocorrelation and partial autocorrelation can be difficult and confusing for beginners to time series […]
