Title: | Analysis of company growth data using genetic algorithms on binary trees | Authors: | JANSSENS, Gerrit K. Sorensen, K LIMERE, Arthur VANHOOF, Koen |

Faster or slower average growth over a time period is explained by building a classification tree containing several categorical variables (both quantitative and qualitative). The technique used - called genAID - splits the population at different levels. It is inspired by the Automatic Interaction Detector (AID) technique to find trees that explain the variability in average growth but uses a genetic algorithm to overcome some of the drawbacks of AID. Classical AID or other tree-growing techniques usually generate a single tree for interpretation. This approach has been criticized because, due to the artifacts of data, spurious interactions may occur. genAID offers the user-analyst a set of trees, which are the best ones found over a number of generations of the genetic algorithm. The user-analyst is then offered the choice of choosing a tree by trading off explanatory power against either the ease of understanding or the conformity with an existing theory. | Notes: | Univ Limburg Ctr, Fac Appl Econ, Data Anal & Modelling Res Grp, B-3590 Diepenbeek, Belgium.
