WebApr 11, 2024 · The nearest neighbor graph (NNG) analysis is a widely used data clustering method [ 1 ]. A NNG is a directed graph defined for a set E of points in metric space. Each point of this set is a vertex of the graph. The directed edge from point A to point B is drawn for point B of the set whose distance from point A is minimal. WebThe graph pie command with the over option creates a pie chart representing the frequency of each group or value of rep78. The plabel option places the value labels for rep78 inside each slice of the pie chart. A two way scatter plot can be used to show the relationship between mpg and weight. As we would expect, there is a negative ...
