First, carefully read Section 8.3 in Introduction to Data Mining. In this assignment, you will write SAS code to examine grid-based clustering algorithm. This algorithm is given on page 645 in Introduction to Data Mining, and it is also provided below. Algorithm 8.4 Basic grid-based clustering algorithm. Define a set of grid cells. Assign objects to the appropriate cells and compute the density of each cell. Eliminate cells having a density below a specified threshold. Form clusters from contiguous (adjacent) groups of dense cells. Complete the following tasks
