## 3. Decaying Averages

The topic for this notebook is Decaying Averages. 1. We will see that Traditional Averages are the best for Static Data Sets, but inadequate for Living Data Streams. Live Data Streams demand Relevance and Sensitivity. 2. We will see that the Decaying Average is both Relevant and Sensitive. It is also easy to calculate. Because of these factors the computation of Decaying Averages yielded an early evolutionary advantage. The Decaying Average led to prediction, which enabled anticipation, which facilitated survival. 3. We will also discover that knowing the Realm of Probability is another helpful predictive measure. To calculate this Realm, we explore the Average Decaying Deviation, or just Deviation. We explore its computation and evolutionary advantages. 4. The final tool we explore is the Average Decaying Directional or just Directional. This allows the organism to compute local tendencies, which also aids the survival of organisms and businesses.
