You must find all the customers that are susceptible to buy your product and send them a brochure or

Lift, ROC, AUC and Gini

Lift, ROC, AUC and Gini One good way to compare different predictive modeling platforms is to compare the models that are produced by these platform.Comparing models across platform is not an easy task. Models can be compared using various criteria’s: 1.    Simple predictive Model Quality (i.e. Height of the lift curve / AUC) 2.    Generalization

Controlling model drift with Timi modeler

Controlling Model Drift With Timi Modeler Timi modeler is a great tool to get models fast. It doesn’t mean they have to be “rough” or ‘inaccurate”. With its default settings, Timi modeler allows citizen data scientists to have, very quickly, a robust model that will have an incredible lift, and identify properly the key variables, and

Recoding variables with R and Anatella

Recoding variables with R and Anatella Variable recoding can be a real pain in the neck. Although there are functionalities to do this in R and Anatella, doing it right is not always easy. For example, when working with Latent Class Analysis, we want to get all our variables in a few categories, and quantiles
