This classification is based on the purpose, horizon, update frequency and uncertainty of the forecast. Nor can we learn prediction intervals across a large set of parallel time series, since we are trying to generate intervals for a single global time series. These characteristics of the problem drive the forecasting approaches.

Markets and competition today are highly dynamic and complex, and the future is characterized by uncertainty – not least because of COVID-19. This uncertainty is currently at the forefront of everyone‘s minds. 75 percent of companies confirm that predictive models provide good forecasts for them, even in volatile markets.

Finally, through a case study of a real-world prediction problem, we also argue that Random Effect models should be considered alongside penalized GLM's even for pure prediction problems. Random effects models are a useful tool for both exploratory analyses and prediction problems. bandit problems).

The values 500 and N /2 are somewhat arbitrary but were chosen in order to obtain a smooth distribution of ROI values and to balance the desire for sufficient variability in the predictions with the need to maintain a large enough training set for each model. A schematic diagram of my modeling process is shown below.
