Problem 3 For this exercise please select a US state or a country to answer the following questions. a. Generate a regular grid of points similar to this one and keep only the points in the US state or country: b. Using the method of spectral decomposition generate data that exhibit geometric anisotropy in the four main directions: N-S, E-W, NE-SW, NW-SE. Note: Use a covariance function and parameters of your choice. c. Detect the anisotropy using a rose diagram and transform the coordinates so that the data are now isotropic. Compute and plot the omnidirectional variogram and fit a model to it. Problem 3 For this exercise please select a US state or a country to answer the following questions. a.
