Great question! I don't have a video going over what spatial weights are quite yet. Essentially spatial weights determine how much influence neighboring locations have on the focal location (the ith element or just one of the elements at a time). There are a ton of ways to do this. To include a distance decay like youve mentioned people tend to use inverse distance weighting. I recommend reading through the geoda documentation its really great! geodacenter.github.io/documentation.html
