by Cluster analysis is a statistical technique used to group data or observations into similar clusters or segments. It is a useful method for exploring data and identifying patterns or similarities within a dataset. Cluster analysis is commonly used in market segmentation, customer profiling, and data mining.
Cluster analysis can be a useful tool for identifying patterns or similarities within a dataset and can be used in a variety of business applications. It is important to carefully choose the variables and clustering algorithm, and to pre-process the data to ensure the validity and reliability of the results.
The basic Steps involved in cluster analysis are as follows:
- Define the problem: Clearly define the problem and the purpose of the analysis. This could involve identifying customer segments or grouping similar products.
- Choose the variables: Choose the variables that will be used in the analysis. These could be demographic, behavioral, or attitudinal variables.
- Select the clustering algorithm: Select the clustering algorithm that will be used to group the data. There are several different clustering algorithms available, including hierarchical clustering, k-means clustering, and density-based clustering.
- Pre-process the data: Pre-process the data by standardizing the variables, removing outliers, and handling missing values.
- Run the analysis: Run the clustering algorithm on the data and identify the clusters or segments.
- Evaluate the results: Evaluate the results of the cluster analysis and interpret the clusters or segments. This could involve creating profiles of each segment, identifying the characteristics that distinguish each segment, and assessing the business implications of the clusters.
