What is an unbiased estimator? Proof sample mean is unbiased and why we divide by n-1 for sample var

Thank you very much

I spent last 2 days trying to wrap around my head estimators and what it means to be unbiased. You explained me in minutes what I could not understand for days. I dont know how to thank you. You are the best. Thanks for the beautiful video

Please more videos on Statistical inferences

if we are given a pdf of 4 values of x with their probabilities in terms of theta, then we find an estimator for the mean theta-hat and then we find the mean square error in terms of theta (should it be in terms of theta?), how can we find if it it mean square consistent. I am unsure because n=4 for my questions so I can't see how it makes sense to consider the limit as n goes to infinity. Please could someone shed some light. Thank you

Very Wonderful 😢🎉❤
God bless you soo much.

amazing ma'am loved it

Thank you so much😊

wow this video is very understanderble

any proof for SDOM? I don't get it why doe have root(N) as denominator in the normal distribution SDOM

Amazing! I was chasing to understand the meaning of biased and unbiased, but this video explains in a very simple way and with great explanation too. Thank you so much for the details.

This is meaningful material. A book I read on the same topic was a eureka moment for me. "Game Theory and the Pursuit of Algorithmic Fairness" by Jack Frostwell
