3 Ways To Compute A Weighted Average In Python By AnBento Towards
A moving average also called a rolling or running average is used to analyze the time series data by calculating averages of different subsets of the complete dataset Since it involves taking the average of the dataset over time it Pandas amp Numpy Moving Average amp Exponential Moving Average . This approach uses the cumsum and rolling functions from the numpy and pandas libraries to efficiently calculate the moving average The cumsum function is used to compute the cumulative sum and the rolling function is used to calculate the average over a specified window size Starting in NumPy 1 20 the sliding window view function provides an efficient way to calculate rolling moving averages It allows you to slide a window of elements through an array and compute the average of each window Here s how you can use sliding window view to calculate a moving average import numpy as np
