👉 The term "autocorrelation" is a statistical concept that refers to the correlation between two random variables. It measures the linear relationship between two variables, which can be affected by factors such as noise or measurement errors. In other words, it attempts to quantify how closely two random variables follow each other over time, taking into account any potential for measurement error or random fluctuations in their values. If there is a significant autocorrelation, it suggests that the relationship between the two variables will be linear
