What is normalization in forecasting?


Normalization in forecasting refers to the process of adjusting historical data so that it can be used to make predictions about future trends. This is typically done by removing any seasonal or cyclical patterns from the data, so that the underlying trend can be more easily identified.


There are several ways to normalize data, but one common method is to use a technique called "differencing." This involves subtracting each data point from the previous one, which can help to remove any seasonality or cyclical patterns. Another method is to divide the data by a moving average, which can help to smooth out any short-term fluctuations.

Normalization is an important step in forecasting because it allows analysts to focus on the underlying trends in the data, rather than being distracted by short-term fluctuations. This can help to improve the accuracy of predictions and enable analysts to identify patterns or trends that might not be immediately obvious.

It's important to note that normalization is a crucial step in the forecasting process, but it's not the only one. After normalizing the data, other steps such as selecting the appropriate forecasting model and properly evaluating the model's performance are also important.

Overall, normalization in forecasting is a technique to make the historical data more suitable for forecasting. It helps to remove any irrelevant variations in the data and to focus on the underlying trends. It's essential to understand the data, and it's variations before making predictions about the future.
