Apr 21 comment Understanding two sided t-test can you explain why this is a two-sided test by looking at the hypothesis? should I not reject if t < 2.262 ? I am very confused :( Apr 21 accepted Frequency of the most frequent word using Zipf's law Apr 21 comment Reduction from Hamiltonian cycle to Hamiltonian path I am confused, is this valid? Apr 20 revised Frequency of the most frequent word using Zipf's law added 128 characters in body Apr 20 comment Frequency of the most frequent word using Zipf's law Thanks for your answer, I am a bit confused from your answer. Why is my reasoning incorrect? Why do you sum all the 1/k ? And how can the most frequent word appear 0.0869 times? I think my gap of knowledge goes beyond this. I have a feeling I confuse frequency with occurrence. But I still do not understand where you bring the new summation in Apr 20 asked Frequency of the most frequent word using Zipf's law Apr 20 asked Understanding two sided t-test Apr 20 comment Simplifying a formula with summation Ok, that is what I was thinking. The average consider it to be a constant, since once I calculate $R_u$ is always calculated. So What I am actually thinking is to subtract $R_u$ to everything in advance Apr 20 asked Simplifying a formula with summation Jan 26 accepted Does infinite tableau branch mean satisfiable formula?
