This transformation has been used frequently in studies involving international trade (under the name ‘revealed comparative advantage’) and in multiple other settings where a total can be disaggregated under at least two independent criteria and thus ...

Focal Location Quotients: Specification and Applications
Geographical Analysis, 2012Location quotients (LQs) are commonly used descriptive statistics in spatial analysis. They are not directly affected by neighbor relationships, and their calculation ignores spatial information. This article computes LQs as focal, rather than strictly local, functions by incorporating the spatial structure of the observations in the reference group in

Clustering: Spatial Autocorrelation and Location Quotients
Advanced Studies in Theoretical and Applied Econometrics, 2018Geographic concentration of employment types frequently yields clusters exhibiting moderate-to-strong positive spatial autocorrelation. Such clusters based upon geographic proximity, and frequently quantified with location quotients, also can relate to local indices of spatial autocorrelation, such as LISA and the Getis-Ord statistics.
