First-order autocorrelation is a condition in which a relationship exists between consecutive residuals. This means that the value of one residual is related to the value of the preceding residual. It is also known as lag 1 autocorrelation. It can be a problem in statistical analyses as it violates the assumption of independence of residuals.
