bisq.dist2weights: bisq.dist2weights
In kmcd39/divflow: What the Package Does (One Line, Title Case)

Uses a Bisquare transformation to turn distances to spatial weights. Transfroms by weight = (1-(ndist/H)^2)^2 for distances less than or equal to H, 0 otherwise. Mimics Bi-square option in lctools::moransI, and I implemented because it is used there and elsewhere to generate spatial weights.

1	bisq.dist2weights(d, cutoff = dst.ceiling, ...)

`d`	distance
`cutoff`	`H` in the formula, where weight is 0.

In analysis I've run for these projects, this function seems to often yield different results from all the other possibilities in a way that makes me feel it's a poor choice for a distance decay function–but this would maybe change with different values for H.
