Cumulative Operations

Overview

Cumulative operations are mathematical operations that involve the accumulation of intermediate results to produce the final result. Examples of cumulative operations include summing a series of numbers, calculating a product of a sequence of numbers, and finding the running total of a list of values. These operations can be useful in numerous situations, such as gaining insights into the data distribution and applying the Pareto principle (aka 80/20 rule) to identify patterns and prioritize action.

The pandas methods that allow us to perform cumulative operations are cumsum(), cumprod(), cummax() and cummin().
