Autocorrelation (or serial dependence) refers to the situation in which the error terms (residuals) in a time series are correlated with each other. Statistically, autocorrelation is defined as the correlation of a random variable with its own lagged values. This concept is particularly important in regression analysis, as it indicates a violation of one of the classical regression assumptions—that the error terms are independent of each other.Autocorrelation is commonly observed in time series

Time series is a sequence of observations of a variable taken at consecutive and regular intervals over time (daily, weekly, monthly, yearly, etc.). In such data, the assumption of independence between observations is generally not valid because observations may be correlated over time. Time series analysis is a set of statistical methods designed to reveal this dependence, model structures that change over time, and make forecasts about the future.Time series are analyzed not only from a statis
