One-dimensional clustering

Speaking of cluster analysis , it is well known that multidimensional data is used as an analysis of sample grouping .

It can be used for the same purpose in one dimension, but in one dimension, it can also be used to convert quantitative data into qualitative data as a method of feature engineering .
