## Data Analytics – CLUSTER ANALYSIS IN R SIMPLIFIED AND ENHANCED

Hits: 184 CLUSTER ANALYSIS IN R SIMPLIFIED AND ENHANCED In R software, standard clustering methods (partitioning and hierarchical clustering) can be computed using the R packages stats and cluster. However the workflow, generally, requires multiple steps and multiple lines of R codes. This article describes some easy-to-use wrapper functions, in the factoextra R package, for simplifying and improving cluster analysis in …

## Statistics with R for Business Analysts – Random Forest

Hits: 62 (R Tutorials for Citizen Data Scientist) Statistics with R for Business Analysts – Random Forest In the random forest approach, a large number of decision trees are created.
