Value weighted index is a market average such as Standard & Poor's 500 Index that takes into account the market value of each security rather than calculating a straight price average. An equal weighted index is a type of weighting that gives the same weight, or importance, to each stock in a portfolio or index fund. The difference is one gives individual value and other gives one value to all.

The nearest-neighbor index measures how clustered or dispersed individual points are in a dataset. It is useful in spatial analysis to identify patterns of clustering or dispersion, assess the degree of spatial autocorrelation, and understand the spatial distribution of data points. A low nearest-neighbor index indicates clustering, while a high index suggests dispersion.
