WebSep 16, 2011 · However, the standard R package for model based clustering mclust apparently will not fit models with mixed data types. The fpc model will, but has trouble fitting a model, I suspect because of the non-gaussian nature of the continuous variables. Should I continue with the model-based approach? I'd like to continue to use R if possible.
WebMar 13, 2012 · k-prototypes clustering might be better suited here. It combines k-modes and k-means and is able to cluster mixed numerical / categorical data. For R, use the … WebIn order to identify the most effective approaches for clustering mixed-type data, we use both theoretical and empirical analyses to present a critical review of the strengths and weaknesses of the methods identified in the literature. Guidelines on approaches to use under different scenarios are provided, along with potential directions for ...
WebIf you have stumbled upon this question and are wondering what package to download for using Gower metric in R, the cluster package has a function named daisy(), which by default uses Gower's metric whenever mixed types of variables are used. Or you can manually set it to use Gower's metric. WebMay 15, 2024 · Clustering in R. Before we perform clustering, we need to run the panel data model first. You can either use the lm function or the plm function from the plm package. I personally prefer the latter over the former. Thus, in this post, I am going to stick with the plm package.
