The type of spatial weights to construct. Defaults to 'Queen'. Other options are 'Rook', 'Binary Distance Band', 'Inverse Distance', 'Lattice', 'K nearest', 'Kernel', and 'Get spatial weights matrix from file'.

Queen which will construct a queen contiguity weights matrix, is more robust and more suitable for areal unit data. The queen criterion is somewhat more encompassing and defines neighbors as spatial units sharing a common edge or a common vertex.
The Rook criterion defines neighbors by the existence of a common edge between two spatial units. Therefore, the number of neighbors according to the queen criterion will always be at least as large as for the rook criterion.
When choosing K nearest , select the nearest number 'Nearest k' in the following options. K-nearest are often used for point data.
When selecting Binary Distance Band , please select the distance threshold 'Threshold' in the following options.
When selecting Inverse Distance , please select the distance threshold 'Threshold' and the corresponding power 'Power' in the following options.
When 'Your own' is selected, please enter the path of the spatial weights matrix in CSV format in the following options.
More details about spatial weights, please see the GeoDa center website .
