I am trying to do clustering on my data which consists of both categorical and continuous variables. I have some questions which I would like to ask:

  1. I am going to use the Gower Distance measure to find the similarties/dissimilarties between data points is that ok?

  2. Can I use K-Means clustering for mixed variables to perform clustering? If not I will use Two-Step Clustering but can Two-Step Clustering be performed in R? Also, if so which Hierarchical Algorithm will I have to use?

Thanks

  • $\begingroup$ @ttnphns - I have researched even before questioning here but there is not like a definite answer to my question as some of the answers are saying you can use K-Means some not and I don't know what I should actually do $\endgroup$ Mar 1, 2019 at 10:39

  • $\begingroup$ Two-step clustering (found in SPSS) acceps interval or nominal variables, but not ordinal or binary. stats.stackexchange.com/a/116859/3277. For nominal ones, it uses log-likelihood distance. $\endgroup$

  • $\begingroup$ @ttnphns - I know about the Two Step Clustering but I am using R and it seems that there is no package that can be applied $\endgroup$ Mar 1, 2019 at 12:49

K-means can only be used in data sets where you can compute the arithmetic mean.

Use hierarchical clustering instead. It can use distance matrixes, including Gower distances.

No, k-means can only work for numeric data. If you have mixed-type data, then you can try k-prototypes, which integrates k-means for numeric data and k-modes for categorical data.
