2 weeks The following is the basic explanation of Multidimensional Scaling-- the 3D graph.
Multidimensional scaling (MDS) allows you to visualize how near points are to each other for many kinds of distance or dissimilarity measures and can produce a representation of your data in a small number of dimensions. MDS does not require raw data, but only a matrix of pairwise distances or dissimilarities.
MDS takes as an input a matrix of interpoint distances and creates a configuration of points by some mathematical matrix manipulation. Ideally, those points are in two or three dimensions, and the Euclidean distances between them reproduce the original distance matrix. Thus, a scatter plot of the points created by MDS provides a visual representation of the original distances. See the attachment below.
