If the size and shape of the SDEs were more closely aligned … then you could say that the distributions were similar and that the surveyed and un-surveyed stores are part of the same “landscape.” Since the ellipse for the un-surveyed locations is much smaller than the ellipse for the surveyed locations, this seems to indicate the opposite … that the un-surveyed locations are actually not representative of the entire county/study area.  The fact that all of the un-surveyed locations fall into the surveyed ellipse is not sufficient evidence, however … The surveyed ellipse contains the ellipse for the un-surveyed locations.  This is the one bit of evidence that the surveyed locations are representative of the landscape. How were the surveyed locations picked?  This is a very important question to answer in order to be confident that the information collected from the survey is representative of all the tobacco retail in the county.   If there was no bias in how the department picked who was and wasn’t going to be surveyed – that would also be evidence. If all of the un-surveyed locations are within x distance of a surveyed location, then you would need to provide justification that the spatial context for locations at the farthest distances would be homogeneous … it looks like there are surveyed locations very close to every un-surveyed location except 2.  Can you provide any evidence that indicates that those locations would not be different from their closest surveyed locations or from other surveyed locations in the study area?  Schools are shown on your map.  Are they important to the analysis?  If they are then it might be helpful to ensure that surveying around each school meets some threshold to give confidence that the un-surveyed locations are not biasing the sample.  Example: for all schools at least 50% of establishments within 1 mile were surveyed.  Those that did not meet this criteria were excluded from the analysis.

Hi Tracy, We tweaked a few things in 10.3 that caused issues with the sample scripts.  Here's an updated version that should work   Thanks for catching that. -Jenora ... View more

I'm glad they got it figured out for you! We found a typo in the code that handles projection conversion.  The majority use meters and feet and it turns out we didn't have a test for miles and we missed it.  Good catch and apologies for the inconvenience... we have fixed this for future releases. -Jenora ...

Hmm ... I didn't encounter either of those problems.  Two quick questions ... 1. Did you start from a blank map?  "Failed to alter the spatial reference" can happen if the dataset is read-only or being locked by another application.  If it was active in another map or project, that could have been the issue... 2. At what point are you trying to view the attribute table?  If the Project tool fails and the attribute table of the layer it was trying to create is empty, that would be expected as the Project tool did not complete. If you cannot view the attribute table after Display XY Data ... that would be a different issue.  This article may have some clues as to why you are not seeing the attributes as expected:  27589 - Import XY data tables to ArcMap and convert the data to a shapefile I guess best case is that you maybe had another map with the same layers open and that is what is causing both issues. Let me know how it goes. Jenora ... View more
