首先,来聊一聊什么是“spatial data”。简单来说,与地理空间信息相关的数据称为空间数据。更具体的,根据Cressie (1993)所述,空间数据可以分为地质数据(geostatistical data),晶格数据(lattice data),和点模式 (point patterns)。其中地质数据包括海拔等数据;晶格数据是指从城市等地区收集的社会经济数据和像素级的卫星...
还有一些其他的选修课,比如说experimental design(实验设计),spatial statistics(空间统计),statistical consulting(统计咨询)等等。 因为很多实验都需要用统计方法进行设计和分析,所以有很多其他学院的grad student都会来上一些基础的统计学课。 💡技能 SAS,R,Python,是我们平时上课会用到的,其中R用得最多(因为免费),...

(Without Spatial) Data science is the study of information and its source, collection, organization, processing, and presentation. It is aninterdisciplinary areathat incorporates elements of statistics, computer science, operations research, mathematics, and programming. ...
Geospatial analyticsis used to add timing and location to traditional types of data and to build data visualizations. These visualizations can include maps, graphs, statistics and cartograms that show historical changes and current shifts. This additional context allows for a more complete picture of...
Similarly, some analyses in spatial statistics provide more accurate results when network distances are used in place of straight-line distances. Consider as an example traffic-incident analysis, which has the aim of locating clusters of traffic accidents, pinpointing their causes, and taking action ...
The TPB density, a vital metric for cell efficiency, can be quantified using the newly introduced "Triple Phase Boundaries" module, which extracts a spatial graph representing TPB from surfaces. To obtain the total TPB length, you can subsequently employ the "Spatial Graph Statistics" module. ...
(nonspatial) statistics, you work with a random sample and try to determine the probability that your sample data is a good representation (is reflective) of the population at large. As an example, you might ask "What are the chances that the results from my exit poll (...
