https://www.statisticshowto.com/serial-correlation-autocorrelation/
WEBSerial correlation (also called Autocorrelation) is where error terms in a time series transfer from one period to another. In other words, the error for one time period a is correlated with the error for a subsequent time period b. For example, an underestimate for one quarter’s profits can result in an underestimate of profits for ...

Serial Correlation in Time Series Analysis | QuantStart
https://www.quantstart.com/articles/Serial-Correlation-in-Time-Series-Analysis/
WEBWhen sequential observations of a time series are correlated in the manner described above we say that serial correlation (or autocorrelation) exists in the time series. Now that we have outlined the usefulness of studying serial correlation we need to define it in a rigourous mathematical manner.
