i working on spring based web application performs predictive analysis based on user historical data , come offers users. need implement predictive analysis or regression kind of functionality gives confidence score/prediction present offers. java developer , looked @ weka, mahout desired result. both tools dont provide documentation , highly difficult proceed them. need suggestion regarding java based analytics api process data using regression or neural networks or decision trees , provides confidence score depicting customers probablity on buying product in future.

any in regard highly appreciable.

i'd advise keep trying weka. it's great tool, not implementation idea of algorithms work you, data looks like, etc. book worth price, if you're not willing buy it, this wiki page might starting point.

it might best start testing, not programming - believe quote goes "60% of difficulty of machine learning understanding dataset". play around weka gui, find out works best , data, , try of meta-classifiers (boosting, bagging, stacking); give great results (at cost of processing time).
