Learning Guide: Calculating Rolling Correlations in R for Time Series Analysis

Rolling correlations are an indispensable analytical method in finance, economics, and data science, providing a measure of the dynamic linear relationship between two time series. Unlike a single, static correlation coefficient calculated across the entire dataset, a rolling correlation calculates this relationship within a defined, shifting time segment, commonly referred to as a rolling window.
