Thank you AndreasHall for the input. It does make sense. There should be a relation between the distance between roads and “trim distance”

But what if the goal of the GWR is to predict individual apartments within the building? In this case, the concept of aggregation may not be meaningful, as the building contains multiple floors, and each floor may have multiple apartments

ArcGIS Pro 3.0.2: Why the GWR requires at least 20 features in order to run? I couldn’t figure out why the GWR requires at least 20 features in order to run. The number of required features (observations) need to be associated to the number of independent variables. Mathematically, based on the OLS, in order to be able to calculate the coefficients of the independent variables and constant, the minimum number of observations need to be greater than or equal the number of independent variables + 1 Is that correct?

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?

ArcGIS Pro 3.0.2: How does the Geographically Weighted Regression (GWR) work in case of multistorey buildings? In case of multistorey buildings, the single point that represents the location of building carries the information of multiple floors. How this can be managed to better apply the GWR?

In the Geographically Weighted Regression (GWR) analysis, I wanted to create W matrix that requires calculating the distance between all points including the point with itself. Is there any other tool that can do this?

ArcGIS Pro 3.0.2: The “generate near table” tool fails to calculate the distance between a point and itself? In the screenshot below, I wanted to calculated the distance between all points including the distance between a point and itself. I was expecting to end up with 10, 000 records but not 9,900 records What could be the issue here?

Many thanks, Robert, for the input and for moving the post to the 'spatial statistics tools' category. I have already referred to several peer-reviewed papers, but I couldn't find a single one that includes a concrete example of how 'W' is calculated. All of them show the equation for 'W' without explaining how it is calculated for a particular point. While I found many examples of how IDW works, there is no similar material explaining how GWR works

ArcGIS Pro 3.0.2: How the weight is calculated in the Geographically Weighted Regression (GWR)? I couldn’t figure out how the weight is calculated in the Geographically Weighted Regression (GWR). For example, in the marked value, the actual price represents the dependent variable where the area and parking are the explanatory variables Now, for this point, how the weights (w) of the area (120 square meters) and parking (1) are calculated to predict the value of the price (97238)? When comparing the GWR with IDW, I found out that in the IDW the values of the surrounding points and distance participate in deriving the point in question by summing and averaging as per the equations below. Then how about the GWR? How the weight is calculated?

I mean that the 'impedance' option is not directly in the ribbon. It's important for it to be there because it indicates the basis on which the entire analysis is performed

Thank you MelindaMorang for the valuable input. I understand now that the cuffoff unit need to match the impedance unit. Could you please provide an example in which cases the “Time Cost” is used? How does it affect the cutoff polygons?
