WebNov 16, 2024 · n c V cluster = (X'X)-1 * Σ u j '*u j * (X'X)-1 j=1 where u j = Σ e i *x i j cluster and n c is the total number of clusters. Above, e i is the residual for the ith observation and x i is a row vector of predictors including the constant. For simplicity, I omitted the multipliers (which are close to 1) from the formulas for V rob and V clusters.

WebFeb 25, 2024 · 1. There is nothing in the k-means objective that requires clusters to have the same number of elements - having a one-element cluster is perfectly fine if it minimizes variance. Because of the squared errors, k-means is quite sensitive to outliers, and that is what you are seeing here supposedly: an outlier. WebNov 11, 2024 · Clustering tries to find structure in data by creating groupings of data with similar characteristics. The most famous clustering algorithm is likely K-means, but there are a large number of ways to cluster observations.
