===Correlated random walks===

Random walks where the direction of movement at one time is [[Correlation and dependence|correlated]] with the direction of movement at the next time. It is used to model animal movements.<ref>{{cite journal |year=1988 |title=Spatial analysis of animals' movements using a correlated random walk model |journal=Journal of Theoretical Biology |volume=131 |pages=419–433 |doi= 10.1016/S0022-5193(88)80038-9|issue=4 |last1=Bovet |first1=Pierre |last2=Benhamou |first2=Simon |bibcode=1988JThBi.131..419B }}</ref><ref>{{cite journal |year=1983 |title=Analyzing insect movement as a correlated random walk |journal=Oecologia |volume=56 |pages=234–238 |doi= 10.1007/BF00379695|pmid=28310199 |issue=2–3 |last1=Kareiva |first1=P.M. |last2=Shigesada |first2=N. |bibcode=1983Oecol..56..234K |s2cid=20329045 }}</ref>
