FAQ: How can I detect/address spatial autocorrelation in my data?

WebThe ﬁrst tests for autocorrelation, based on the alternative of an AR(1) model of the error process, only considered that possible departure from independence. From a pedagogical standpoint, such a test is dangerous, as a failure to reject may be taken as a clean bill of health, implying the absence of serial correlation: which it is not.
