SAS Warranty Analysis 4.2 includes two analytics, Multivariate Statistical Drivers and Text Analysis, and the functionality Find Similar Comments in the Details Table analysis that use data mining and text mining techniques to analyze warranty data. Multivariate Statistical Drivers uses decision trees to determine which set of reporting variables are statistically significant for explaining variability in warranty claim rates. Text Analysis runs text mining on a text variable, clusters observations, and performs a decision tree analysis to determine which set of reporting variables are best at differentiating each cluster from the overall population. Find Similar Comments finds the requested number of comments that are most similar to a selected comment and outputs a distance metric that provides a relative measure of similarity.
