The vertical scale on the dendrogram represent the distance or dissimilarity. Each joining (fusion) of two clusters is represented on the diagram by the splitting of a vertical line into two vertical …

2020年11月22日 · I'm quite new to cluster analysis and I was trying to perform a hierarchical clustering algorithm (in R) on my data to spot some groups in my dataset. Initially, I tried with …

Cutting a dendrogram at a certain level gives a set of clusters. Cutting at another level gives another set of clusters. How would you pick where to cut the dendrogram? Is there something …

2016年9月3日 · You've mixed two separate questions in one. Your 1st Q is actually about hierarchical cluster analysis, not dendrogram. (It is possible to do the HCA and save a range of …

I have dendrogram and a distance matrix. I wish to compute a heatmap -- without re-doing the distance matrix and clustering. Is there a function in R that permits this?

In the dendrogram, the y-axis is simply the value of this distance metric between clusters. For example, if you see two clusters merged at a height x x, it means that the distance between …

2023年5月16日 · I have been using this dendrogram to visually identify clusters, and then clusters within the clusters, in order to understand product groupings. The process of manually …

2015年1月9日 · 1 1 on the problem of dendrogram of 's method. Different clustering programs may output differently transformed aglomeration coefficients for Ward's method. Hence their …

2021年3月25日 · I have viewed this clustering with an interactive dendrogram, but I want to understand how to interpret this better. A static view of my plot looks like this: The x-axis is all …

Now to turn the resultant dendrogram into a number of groups of points (flat clusters), I want to choose which level to cut the tree at (the same as choosing the number of clusters).
