Exploratory data analysis methods
This chapter emphasizes the need to carry out Exploratory Data Analysis (EDA) before embarking on any modeling endeavor. EDA techniques introduced include non-spatial techniques such as histogram, pairwise scatter plots; spatial methods such as variogram and Kriging; and temporal exploration such as time series plots. In particular, the chapter explores the following four data sets which are provided in the bmstdr package.
- nyspatial : point referenced spatial air pollution data from New York,
- nysptime: point referenced spatio-temporal air pollution data from New York,
- engtotals: areal unit data on Covid-19 mortality in England,
- engdeaths: areal unit weekly temporal data on Covid-19 mortality in England,
