I'm interested on acquiring a strong foundation in statistics. I have just finished Introduction to Probability by Joe Blitzstein and I'm looking for a good book on statistics before moving to The Elements of Statistical Learning.
I have searched through many posts across this site and I'm not sure about which book to pick in order to do so. I'm between Casella and Berger Statistical Inference and Wasserman All of Statistics. Since my mid term goal is research, maybe Casella and Berger would be a better choise, since seems more in depth and focused to traditional statistics, but I'm not sure.
Which one would you recommend me?
