The Predictive Model for Archaeological Sites in the Hopi Reservation of Northeastern Arizona was developed to assist archaeologists in minimizing their study area for locating archaeological sites. Extensive research exists on predictive models for locating archaeological sites since the 1970s because many study areas are too large for archaeologists to cover on foot. The archaeological site types for these models were Habitation, Rock Art, and Scatter and were established between 500-1500 C.E. The independent variable categories for these models developed in ArcGIS 10.2 were based on topography, water resources, and vegetation. The logistic regression model in the Statistical Package for the Social Sciences (SPSS) was the selected statistical approach for building the predictive models. The final seven archaeological site type predictive surfaces were then created in the ArcGIS 10.2 Raster Calculator based on the coefficients created and statistically significant independent variables determined from the logistic regression models
