As an exploratory technique, it is useful in examining unrecognized dimensions about products and in uncovering comparative evaluations of products when the basis for comparison is unknown. Advantages:Permits analysis of large numbers of variables that would be too cumbersome and time consuming to analyze individually. If your company operates several chains of stores, you can experiment with putting . It is very useful for exploring and identifying patterns in datasets as not all data is tagged or classified. The purpose of discriminant analysis is to correctly classify observations or people into homogeneous groups. (Examples: Are people clicking the green or the red click button more? The quality of the data refers to how normally distributed the data are. Kruskals Stress measure is a badness of fit measure; a stress percentage of 0 indicates a perfect fit, and over 20% is a poor fit. To recap, here are some key takeaways: So what now?
