W row-standardised; B binary; C \(n^* g/D\); U \(g/D\); minmax
\(g/\min(\max rowsum, \max colsum)\) (Kelejian and Prucha 2010); S
\(n (g_{ij}/q_i)/Q\), \(q_i = \sqrt{\sum_j g_{ij}^2}\) (Tiefelsdorf,
Griffith and Boots 1999), with \(n^*\) the units having neighbours and
\(D\) the weight sum. Identical to the Python arm
morie.fn.swutil.weights_style.
Usage
WeightsStyle(W, style = "W")
Arguments
- W
Square weights matrix.
- style
One of W, B, C, U, minmax, S.
