Lauren Scott, Ph.D.
Where do statistics, spatial statistics, and geostatistics fit in GIS projects? Dr. Lauren Scott, a product engineer on Esri's geoprocessing team and an expert in the use of statistics in a geospatial context, answers that question and others in an interview conducted by Matt Artz, Esri's GIS and science marketing manager and editor of the GISandScience.com blog.
At Esri, Scott is responsible for software support, education, documentation, and development of spatial statistics tools in ArcGIS. She received her Ph.D. in 1999 from the Joint Doctoral Program at San Diego State University and the University of California, Santa Barbara. She holds an M.A. and a B.A. in geography from California State University, Fullerton.
Artz: How do traditional statistics, spatial statistics, and geostatistics differ from each other?
Scott: Traditional or non-spatial statistics are typically used in two different ways. In the first case, we have a large set of data values that we want to understand, and we can use descriptive statistics to try to summarize them. In the second case, we may have a set of samples and we want to know how reflective those samples are of the broader population.
Artz: Where do spatial statistics come into play?
Scott: Spatial statistics were designed specifically for use with spatial data-with geographic data. These methods actually use space-area, length, proximity, direction, orientation, or some notion of how the features in a dataset interact with each other-right in the mathematics. That's really what makes spatial statistics different from traditional statistical methods.
Anything new about stirling engines in Cal?
Looking for an update. Everything I find from google news is almost a year old. This is from the stirling engine deal with Southern Edison to build a 500MW plant outside of LA.
What geographical areas are best suited for a solar dish farm?
The southwest region of the United States is ideally suited for this. In fact, a solar farm 100 miles by 100 miles could satisfy 100% of the Americaâs annual electrical needs. Solar technology primarily addresses the peak power demands facing utility companies in the Southwest U.S. and other solar-rich areas.
The cost of living and job markets are better than the national average, but the best job strategy is not to go for averages, but look at your specific skills and experiences, figure out which careers that relates to, and then go to that geographical area:
technology - Silicon Valley
finance - New York
There are other factors to consider. How important are mountains? the ocean? good weather? I have met many midwesterners in Acapulco during the winter, and none ever told me
"I got to get back to Omaha. I just miss those snow covered plains."
4,000 Year Old Greenlander
WASHINGTON (Reuters) â Scientists have sequenced the DNA from four frozen hairs of a Greenlander who died 4,000 years ago in a study they say takes genetic technology into several new realms.
Surprisingly, the long-dead man appears to have originated in Siberia and is unrelated to modern Greenlanders, Morten Rasmussen of the University of Copenhagen and colleagues found.
"This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit," the researchers wrote in Thursday's issue of the journal Nature
