Stochastic Solutions delivers consulting and software in the area of data analysis with a specific focus on customer behaviour modelling. We produce our own software for data analysis (Miró and the Artists Suite) which we use in conjunction with standard (mostly free and open source) software to deliver client solutions. We combine a modern software engineering mindset with deep knowledge and experience of large-scale data and predictive modelling. As a result, we deploy high-quality, tested, large-scale self-monitoring modelling and analysis systems to our clients, using a mixture of standard, packaged and custom software. We place great emphasis on correctness and robustness of solutions, and carry over many of the ideas from software engineering (such as test-driven development, regression testing, automation, revision control) to the analytical domain, ensuring that as we develop and when we deliver solutions to clients, there can be confidence in the correctness and reliability of those solutions.
