I'm David Refaeli, M.Sc. in Statistics and Data Science from Tel-Aviv University. I make these videos to really hone topics which I found a bit challenging, and to share this knowledge with others who might struggle like I did. Mistakes are possible (please comment or send me an e-mail if you believe you found one!). Paypal.Me: paypal.me/MeerkatStatistics (preferred)
