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^{3…
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…
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…
The Impossibility Region for Detecting Sparse Mixtures using the Higher Criticism
David L. Donoho, Alon Kipnis
Consider a multiple hypothesis testing setting involving rare/weak effects: relatively few tests, out of possibly many, deviate from their null hypothesis behavior. Summarizing the…
Higher Criticism to Compare Two Large Frequency Tables, with sensitivity to Possible Rare and Weak Differences
David L. Donoho, Alon Kipnis
We adapt Higher Criticism (HC) to the comparison of two frequency tables which may -- or may not -- exhibit moderate differences between the tables in some unknown, relatively smal…
Mean Estimation from Adaptive One-bit Measurements
Alon Kipnis, John C. Duchi
We consider the problem of estimating the mean of a normal distribution under the following constraint: the estimator can access only a single bit from each sample from this distri…
