I have 30,000 points and am trying to use Ripley's K but no luck. Any suggestions would be appreciated?
I am running Global Moran’s I with an iterator (220,000 records grouped by a field called M_GEOID_2, which has 927 different values). What I need to do is change both the output feature class name and the HTML report file name to reflect those groups. The current output features have identical names taken from the input…
Would Esri be open to renaming “Confidence” to “Confident Interval” or “Confidence Int.” for OHSA results? I realize this could be rectified quickly by the user by simply renaming it within the "Contents" pane. However, I think it's important Esri considers the potential misinterpretation of the OHSA results by designating…
Does anyone know how to create a space time cube with 2 or more variables? I am very interested in the newly introduced "Time Series Cross Correlation" tool and it need a space time cube with 2 or more variables as input. I have tried using "Create Space Time Cube From Multidimensional Raster Layer " tool but the result…
Using ArcGis 10.8 Whe using arcpy.GeographicallyWeightedRegression_stats() or arcpy.stats.GeographicallyWeightedRegression(), the bandwidth obtained is different than those equivalents obtained trough R software (spgwr AND GWmodel), which are consistent between them Reproducible example: using columbus dataset (library…
I am using 5 rasters in my model to predict a soil property point data. I am wondering what it means when you have a low variance explained 22% (model bag of errors), however in my training data regresssion diagnostics, the R2 is 89% and the SMSE and SE are also low. Also, when I look at my residuals the model appears to…
For a points file, I used 'conceptualization of spatial distance' for Moran's I as: 1 - Zone of indifference 2 - Inverse distance 3 - Inverse distance squared The Moran's I was statistically significant only for 'inverse distance'. Subsquently I used hot spot analysis and found statistically significant hot and cold spots.…
I have data points (points shapefile) on the proportion of a certain disease, with values ranging from 0 to 1. After creating a kriged surface, the proportions ranged from 0.043 to 0.756. I need to understand why this discrepancy occurred. For reporting these findings in a scientific journal, would it be appropriate to use…
Using point data, I ran Moran’s I with a distance band of 100,000 meters to ensure that each point had at least one neighbor and obtained statistically significant result. Now, when trying to run Kriging, I am unsure whether to use the ‘fixed’ or ‘variable’ option for the ‘Search Radius Settings.’ I am particularly…
Hi, When analyzing point data spanning about 26 degrees, I obtained a Moran's I value that is not statistically significant. However, after projecting my shapefile, the p-value becomes highly significant. Although the area covered by the points is definitely less than 30 decimal degrees, I'm uncertain about how to proceed.…
