Very nice explanation! Can you comment on variance and hot deck, please? Doing the quick math, the variance of the initial data set is 0.7. With the mean added it is 0.46. With hot deck it is 0.49. So hit deck solves the variance con a bit, obviously, but is that perception generalizable?? Great stuff!!

Thanks for the amazing videos. Just one quick question. If this was a machine learning problem and sex was our target variable would it still be ok to apply this method without having concerns of introducing bias to our model?

Hey, I am currently doing my thesis and working with economic surveys on a few countries and need to apply a hotdeck with 5 variables to impute declared income. I was wondering whether you do paid tasks such as this one I'm describing? Thanks
