Thank you, Eric Krause, for your input.
I'm currently grappling with how to determine the W matrix for a specific prediction. To clarify, let's consider a concrete example.
In the screenshot below:
- Point #7 represents the prediction point.
- The bandwidth is set at 120 meters.
- Within this 120-meter bandwidth, there are 16 points, including the prediction point.
Now, we can calculate the influence of the 15 neighboring points within the 120-meter bandwidth using the following equation:
Wij = e^(-dij/b)
As we have 16 points, this means that we need to calculate the following:
W17, W27, W37, W47, W57, W67, W77, W87, W97, W107, W117, W127, W137, W147, W157, W167
Where:
W17 = e^(-d17/b)
W71 is the influence of the point#1 on point #7 (prediction point)
d71 is the distance between point#1 and point #7
is this approach correct in constructing the W matrix for the prediction of point#7?
