Sharp Lower Bound on the Minimax Risk for Multinomial Uniformity Testing via a Conditional Central Limit Theorem
Alon Kipnis
We study minimax goodness-of-fit testing for uniformity from multinomial observations over categories against departures of size . Writing $u_n:=ε_n^2 n\,N^…

The Minimax Risk in Testing Uniformity over Large Alphabets under Missing-Ball Alternatives
Alon Kipnis
We study the problem of testing the goodness of fit of categorical count data to a Poisson distribution uniform over the categories, against a class of alternatives defined by excl…

Higher criticism for rare and weak non-proportional hazard deviations in survival analysis
Alon Kipnis, Ben Galili, Zohar Yakhini
We propose a method for comparing survival data based on the higher criticism of p-values obtained from multiple exact hypergeometric tests. The method accommodates non-informative…
