Issues with Emerging Hot Spot Analysis variables

Hello everyone,

I am currently having issues to understand the variables I get after executing the Emerging Hot Spot Analysis tool. They actually seem pretty different than what is indicated on the documentation : https://doc.esri.com/en/arcgis-pro/latest/tool-reference/space-time-pattern-mining/emerginghotspots.html?tabs=dialog

First, correct me if I am wrong, but from what I've understood from a previous post (https://community.esri.com/t5/arcgis-pro-questions/question-about-emerging-hot-spot-analysis-results/td-p/1190724), there are some variables present inside the summary table on the documentation page that are either included inside the 2D output feature (the "trend" variables mostly), or either included inside the 3D STC after using "Vizualise STC in 3D" with the "Emerging Hot Spot results" option (z-score, p-value and bin value of the Gi* itself).

However, the names of my tables fields are not the same than the ones of the documentation :

OBJECTID

Time Step ID

Start Date

End Date

Time Step ID Exaggeration

Element

Location ID

VALUE_MEAN_ZEROS

Hot Spot Analysis z-score (VALUE_MEAN_ZEROS)

Hot Spot Analysis p-value (VALUE_MEAN_ZEROS)

Hot Spot Analysis bin (VALUE_MEAN_ZEROS)

Attribute table of the 3D layer

OBJECTID

Location ID

Category

Pattern Type VALUE_MEAN_ZEROS

Percent Significant Hot Spot

Percent Significant Cold Spot

Trend z-score VALUE_MEAN_ZEROS

Trend p-value VALUE_MEAN_ZEROS

Trend bin VALUE_MEAN_ZEROS

Sum VALUE_MEAN_ZEROS

Min VALUE_MEAN_ZEROS

Max VALUE_MEAN_ZEROS

Mean VALUE_MEAN_ZEROS

Standard Deviation VALUE_MEAN_ZEROS

Median VALUE_MEAN_ZEROS

Shape_Length

Shape_Area

Attribute table of the 2D layer.

I suppose that on the 3D layer, "Hot Spot Analysis z-score/p-value/bin value (VALUE_MEAN_ZEROS)" is the equivalent of "EMERGING_{ANALYSIS_VARIABLE}_HS_ZSCORE" on the documentation.

My main problem is with the 2D table. There are two "Trend" variables on the documentation ("{ANALYSIS_VARIABLE}_TREND_ZSCORE" / "EMERGING_{ANALYSIS_VARIABLE}_TREND_ZSCORE"). From what I understand, the first one calculates Mann-Kendall on the location's values (for example NDVI in my case) while the second one calculates M-K on location's Gi* values. In my 2D table, there is only one "trend" value, which is "Trend z-score/p-value/bin (VALUE_MEAN_ZEROS)". Then, I would like to know to which one of the two variables mentioned on the documentation this variable refers to.

Does anyone in Esri Spatial Statistics Team (@LynneBuie, @LaurenGriffin) has an idea about what this "Trend z-score/p-value/bin (VALUE_MEAN_ZEROS)" refers to ? Or is there a problem with my software's version ? I precise that I have ArcGIS Pro latest version (3.7. while I'm writing this post).

Thank you very much for your eventual responses and sorry for my bad english.
