I know that this question has been asked in other ways but I am not still able to find an answer for it. I want to calculate the population-weighted centroids of census tracts within the Contiguous US using the census block populations.  I am using the Mean Center and I have defined the weights as census block populations, and for the Case field, I used the census tracts FIPS Code. There are 83,776 tracts in the Contiguous US but the outcome has only 28,798 records. And most of the points are not projected on the right tract (for instance, the centroid of a tract in NY is shown in FL).  I have also used the "USA_Contiguous_Equidistant_Conic" projection system for all my data and also my main map. The Datum is also NAD83. I know that Census provides Population Mean Center but I want to find a way to get those results by myself. Please assist me if you can. Thank you ... View more

Hi, I am trying to apply GWR on patients' claims data. for every record of patients, I have demographic info and their ZIP Codes. so if I plot them, they will be mapped on each other at the centroid of ZIP Codes. 1. GWR works on my data but I wonder whether the results are reliable for points data like this? 2. I have a binary outcome and several binary independent variables. While I can choose Binary for the outcome variable in the GWR settings, can I use binary independent variables (or even categorical variables with more than 2 classes) in GWR? if yes, I wonder how I should interpret the results for independent variables' coefficients?  let's say I code males as 0 and females as 1. so the coefficients should be interpreted for females as they are coded 1? what if they are coded as males with 1 and females with 2? Thanks for the feedback in advance. ... View more

I want to develop a multivariate logistic regression to model the odds of opioid overdose deaths at the ZIP Code level.  Since the logistic regression does not handle spatial autocorrelation, I need to check whether my dependent/outcome variable is spatially autocorrelated or not (measuring the Moran’s I on the occurrences of opioid overdose death). I wonder if the outcome was spatially autocorrelated, how I can address that in ArcGIS Pro? I know that people use the Bayesian hierarchical spatial model to account for spatial autocorrelation but how can I use such a method in ArcGIS? Does the GWR method account for spatial autocorrelation? ... View more

I have the ArcGIS Pro 2.2.1 with all the features installed. I am trying to create space-time cube using the tool, however, when I try to run it, I get this error: Error 001022: This tool requires a projected coordinate system. I have defined both "Current XY" and "Current Z" coordinate of the map (Utah; as can be seen attached) to GCS North American 1983 and NAD 1983 respectively, so I have no idea why I get this error again and again. Do you have any idea? Moreover, I have also used the "Project" tool to project the Layer (Utah_Zipcode_Time) that I want to use in the "Create Space Time Cube" tool. This is a shapefile with a time-based variable, count of incidence, and many other variables in it. ... View more
