The bivariate LISA is the crossproduct of the standardized values of one variable at location </SPAN><SPAN style="font-style:italic;">i</SPAN><SPAN> (temperature) with those of the average neighboring values of the second variable (depth). You are testing whether localized correlations between values at location </SPAN><SPAN style="font-style:italic;">i</SPAN><SPAN> and those of its neighbors are significantly different from what you would observe under spatial randomness. This would mean that a lo-hi outlier indicates that standardized temperature are significantly correlated with standardized depth.</SPAN></BODY></HTML> Fri, 05 Apr 2013 20:48:53 GMT https://community.esri.com/t5/spatial-statistics-questions/cluster-and-outlier-for-temperature-depth/m-p/49206#M169 JeffreyEvans 2013-04-05T20:48:53Z
