~Hello everyone in this tutorial, I am going to cover almost all concepts involved in cluster analysis, starting from how to find an optimum number of clusters using wss plot function, silhouette method using factoextra package and also by using NbClust package, for k-means and hierarchical clustering algorithms, in hierarchical clustering I will explain about dendrograms, how to plot, export and hang them. In this tutorial, I will also show how to find the inter and intracluster distances using an R package called clv. Finally how to find the cluster means or average https://www.seevid.ir/fa/w/Hyqr4m7tle0 Introduction https://www.seevid.ir/fa/w/Hyqr4m7tle0 Preliminary steps https://www.seevid.ir/fa/w/Hyqr4m7tle0 k means https://www.seevid.ir/fa/w/Hyqr4m7tle0 Opt no of clusters https://www.seevid.ir/fa/w/Hyqr4m7tle0 Hierarchical clustering https://www.seevid.ir/fa/w/Hyqr4m7tle0 Cluster distances https://www.seevid.ir/fa/w/Hyqr4m7tle0 Cluster means Other youtube videos Coding 1) https://www.seevid.ir/fa/w/5eDqRysaico 2) https://www.seevid.ir/fa/w/PX5nSBGB5Tw Theory 1) https://www.seevid.ir/fa/w/Se28XHI2_xE 2) https://www.seevid.ir/fa/w/QXOkPvFM6NU 3) https://www.seevid.ir/fa/w/4b5d3muPQmA 4) https://www.seevid.ir/fa/w/7xHsRkOdVwo Descriptive ~NbClust 1) https://www.rdocumentation.org/packages/NbClust/versions/3.0/topics/NbClust ~Finding the optimum number of clusters 1) https://uc-r.github.io/kmeans_clustering 2) https://stackoverflow.com/questions/15376075/cluster-analysis-in-r-determine-the-optimal-number-of-clusters ~Distances 1) https://www.geeksforgeeks.org/ml-intercluster-and-intracluster-distance/ Script https://docs.google.com/document/d/19owjlv9cpVDrJEWsYUgTVdDk9_2knkBVfLYnZefGyT0/edit?usp=sharing
