Matej is not only an excellent mathematician, he is an exemplary teacher. I am good at many things, but selecting and implementing the right statistical analysis for my dissertation was a step beyond my capability. Matej collaborated with me and led me through the analysis I needed to effectively make the points I needed to make from the raw data received from my doctoral survey. I would absolutely recommend his services! Reasonably priced, excellent customer service, and very pleasant interactions as he helped me along. Every question I had was answered within an hour of my asking it. Matej is more than a statistical resource. He makes himself a partner in your journey and a key component in your success. I wholeheartedly recommend and endorse his service!
