Thanks for sharing your knowledge. I'm amazed to see you write in that manner, which kind of reminded me of Da Vinci's mirrored writing. I've only recently known about bootstrapping and intend to know more. Some people said that bootstrapping is the "non-parametric equivalent of multiple regression". I would really appreciate if you could share your opinion concerning this claim. :-)

Thanks! this video help me a lot to understand bootstrap.
