Consider the following dataset. You can calculate variograms by hand. In general, you would need more data to generate stable variograms. The data are located at the grid centers of a square grid of side $1\mathrm{m}$. The directions to be studied are two main directions ${\alpha }_1$ and ${\alpha }_2$ and two diagonal directions ${\alpha }_3$ and ${\alpha }_4$. Note that the basic lag size in the main directions is $1m$ while it is $\sqrt{2}m$ in the diagonal directions. 1. Calculate the semivariogram values for four lags in the four directions. Tabulate the results with the number of pairs and the semivariogram values for each lag and direction. Plot the experimental semivariogram points for each direction and comment on any anisotropy.
