Market Segmentation - Algorithms and Approaches

Algorithms and Approaches

Any discrete variable is a segmentation. For instance, customers might be segmented by gender ('Male' or 'Female') or attitudes ('progressive' or 'conservative'). Numeric variables may be discretized to become segmentations, such as age ("<30" or ">=30") or income ("The 99% (AGI= US $300,000)").

Segmentations can be obtained by any number of approaches. Minimally, an existing discrete variable may be chosen as a segmentation, also called "a priori" segmentation. At the other extreme, a research project may be commissioned to collect data on many attributes and use statistical analyses to derive a segmentation, also called "post-hoc" segmentation. In between, qualitative knowledge of the market based on experience may be used to identify divisions that are likely to be useful.

Common statistical techniques for segmentation analysis include:

  • Clustering algorithms such as K-means or other Cluster analysis
  • Statistical mixture models such as Latent Class Analysis
  • Ensemble approaches such as Random Forests

Latent class analysis and k-means analysis may be viewed as identifying new variables that maximize the sum of mutual information between the segmentation variable and a set of basis variables.

Famous quotes containing the word approaches:

    The Oriental philosophy approaches easily loftier themes than the modern aspires to; and no wonder if it sometimes prattle about them. It only assigns their due rank respectively to Action and Contemplation, or rather does full justice to the latter. Western philosophers have not conceived of the significance of Contemplation in their sense.
    Henry David Thoreau (1817–1862)
