'Problem 3 (20 points) Use the similarity matrix as follows to perform single and complete link hierarchical clustering: Show your results by drawing dendrogram with R The dendrogram should clearly show the order in which the points are merged. Please show your R code: pl p2 p3 p4 p5 pl 1.00 0.10 0.41 0.55 0.35 p2 0.10 1.00 0.64 0.47 0.98 p3 0.41 0.64 1.00 0.44 0.85 p4 0.55 0.47 0.44 1.00 0.76 p5 0.35 0.98 0.85 0.76 1.00'

In table 4.2 is given the pairwise cityblock distances between 8 observations along with a description of the dataset. What can be concluded about the similarity of observation o1 and o3? Table 4.2. Pairwise Cityblock distance, i.e d(oi, oj) = ||xi - xj||1 = sum(k=1 to M) |xik - xjk|, between 8 observations. Each observation oi corresponds to a M = 15 dimensional binary vector, xik in {0, 1}. The blue observations {o1, o2, o3, o4} belong to class C1 and the black observations {o5, o6, o7, o8} belong to class C2. A COS(o1, o3) = 0.533 B J(o1, o3) = 0.533 C SMC(o1, o3) = 0.533 D There is insufficient information to draw specific conclusions. E Don't know.

10. State if the triangles in the pair are similar. If so, complete the similarity statement. * A 50 40 C 20 B E 25 20 D 10 Yes, they are similar by SSS~ Yes, they are similar by AA~ Yes, they are similar by SAS~ No, they are not similar If you answered "Yes" for the previous question, type the similarity statement using only uppercase letters and a "~" between (no triangle symbol needed). For example: "ABC~PTO". If you answered "No", type "No" for this answer. *
