live in food deserts, depending on how the tract is measured. To meet the official criteria, an area must be classified as a low-income census tract, and residents must live a certain distance from a large grocery store. In urban environments, this distance...
So when it comes time to get a new one, “I would ask people to look to replace it not just with another roof built to code but to something that's built above code,” says Papadopoulos. “You'll have a stronger roof on your house that in case of a tornado or hurricane is less ...
Not only is it intractable to ensure that you've found an optimal solution, it is also unrealistic to try to identify a clustering algorithm that will perform best for all possible types of data and scenarios. Clusters come in all different shapes, sizes, and densities; attribute data can...
Between 1970 to 2015, the number of studies we reviewed has doubled for every decade. We also coded the geographic unit of analysis (e.g., address, street segment, block, block-group, census tract, neighborhood, county),Footnote 12 measures of crime (e.g., calls for service, incident ...
Step 4. Your turn! Use this same process for the state and tract layers. Decide if you should adjust the maximum value, the minimum value, or both. To classify or not to classify By default, ArcGIS Online will suggest a continuous (unclassed) size ramp. In the map you just made, the...

using high-quality data from the Brain Initiative Cell Census Network (BICCN), we systematically investigate marker replicability for 85 neuronal cell types. We show that, due to dataset-specific noise, we need to combine 5 datasets to obtain robust differentially expressed (DE) genes, particularly...
The much much harder part is the post-processing. Negative counts and fractional counts are unacceptable to data users, but we also don't want a spike at zero. The most challenging part, however, is the requirement for sums adding up throughout theCensus Geography Hierarchy. ...
I'd also be interested to learn where to look up the "spot price" you mention in the listing. (Which again, of course, requires me to know what alloy this actually is.) Thanks! While I waited for him to reply, I measured the little ingot's density. ...
Financial institutions are required to comply with Regulation C and must report their data each calendar year. The data is broken up by census tract to show mortgage origination, purchases of homes, and home improvement loans. Regulation C requires these institutions to also furnish data about the...
