Statistical analysis often involves calculating various measures on large datasets. Speed and efficiency are crucial, especially when dealing with real-time analytics or massive data volumes. The TidyDensity package in R provides a set of fast cumulative functions for common statistical measures like mean, standard deviation, skewness, and kurtosis. But just how fast are these cumulative functions compared to doing the computations directly? In this post, I benchmark the cumulative functions against the base R implementations using the rbenchmark package.
