EDA for analysis of nominal variable with high cardinality












1












$begingroup$


I have a nominal variable (car model) with very high cardinality (~8500 labels) and I would like to analyse its relation with a binary target variable. While I can create logical groups and compare the distribution of target variable for each of the groups, can anyone suggest if there are any superior techniques/visualization tools for this type of analysis?

          You can calculate mean target for each categorical variable and compare its values.
          In pandas this can be done easily: df.groupby('categorical_feature').target.mean()



          Then you can make a histogram to compare the approach. I also, seaborn has a catplot, where it do the same as above in a bar plot format, showing mean value for target variable based on each categorical one.
