What is the four point centred moving average?

The four-point centered moving average is a statistical method used to smooth a time series by averaging a set number of data points around a central point. Specifically, it takes the average of four consecutive data points, using two points before and two points after the central point. This technique helps reduce fluctuations and noise in the data, providing a clearer trend. It is particularly useful in analyzing seasonal data where trends need to be discerned over time.
