What is the meaning of autocorrelation?

Autocorrelation is a mathematical representation of the degree of similarity between a given time series and a lagged version of itself over successive time intervals.

What is the most common form of autocorrelation?

The most common form of autocorrelation is first-order serial correlation, which can either be positive or negative. Positive serial correlation is where a positive error in one period carries over into a positive error for the following period.
