Previsão Naïve

The Naïve Forecasting is a simple technique of time series forecasting that is based on the idea that the future value is related to the current value. The formula for this technique is simple: y_{t+1} = y_t, where y_t is the value at time t and y_{t+1} is the predicted value for time t+1.

This technique is useful when there are not many data available or when the time series is stable and there are not many fluctuations. Besides, it is a good option to test the consistency of the data before applying more advanced forecasting techniques.

However, it is important to note that the Naïve Forecasting is not a robust technique and may not be effective in cases where there are many volatility or trend in the time series. In these cases, it is recommended to use more advanced forecasting techniques, such as regression or machine learning models.

When using the Naïve Forecasting, it is important to consider common precautions, such as the choice of the time period for the forecast and the consideration of possible measurement or data collection errors.
