"The first principle is that you must not fool yourself and you are the easiest person to fool."

Richard P. Feynman

Mathematician, data scientist, focused on predictive modeling using R

Probability theory and statistics have been of little concern to me during my studies and today I fear that I have forgotten most of it. To improve my knowledge I am, besides self study trying to participate actively on cross validated, asking and answering questions which I find is a great way to learn. I hope that my questions and answers help others as well.
