In this issue we explain some of the statistics that RDS reports for classification models and dig into some data from the tax authorities!
Evaluating a classification model - What does precision and recall tell me?
| Once you have created a predictive model, you always need to find out is how good it is. RDS helps you with this by reporting the performance of the model as estimated from data not used for creating the model. Read this article in order to understand why you should pay attention to precision and recall. |

Re:analysis - tax audit data mining
| In the last issue of the newsletter, we went mushroom hunting. In this issue we will be doing something completely different; hunt for unpaid taxes. This exercise is based on real data. Follow the tax auditor's quest for the unpaid taxes in the data and see what conclusions can be made and what actions follow. Tax audit data available for download. |

October 2006 Welcome to the first periodic newsletter since our launch of the P3 license model. The first few weeks have been exciting with many new RDS users from all over the globe. What data-mining method should I use? Re:analysis  | In this issue we are dissecting no less than two data sets. Since it is mushroom season here in Sweden, we went through some data to see if there is something to learn before going to the forest to stock. Data available for download. | | Mushroom data mining season » |
| For those of you chemically inclined, we have performed a re-analysis of a toxicity classification data set that we published earlier this year. This time we used other descriptors. Data available for download. | | Phenol toxicity classification » |
