So when you try to plot, you have 10 x values and only 1 y value – G. Anderson. Nov 10, 2024 at 16:38. Thanks G. Anderson. Well explained. – GKC. Nov 10, 2024 at 16:59. In cluster analysis, the elbow method is a heuristic used in determining the number of clusters in a data set. The method consists of plotting the explained variation as a function of the number of clusters and picking the elbow of the curve as the number of clusters to use. The same method can be used to choose the … See more Using the "elbow" or "knee of a curve" as a cutoff point is a common heuristic in mathematical optimization to choose a point where diminishing returns are no longer worth the additional cost. In clustering, this … See more The elbow method is considered both subjective and unreliable. In many practical applications, the choice of an "elbow" is highly ambiguous as the plot does not contain a sharp elbow. This can even hold in cases where all other methods for See more There are various measures of "explained variation" used in the elbow method. Most commonly, variation is quantified by variance, … See more • Determining the number of clusters in a data set • Scree plot See more
