Abstract

We studied simultaneous recovery of a latent group count, subject partition, and signature means from multiview ordinal ranks. A normalized reference rearrangement score is an affine Spearman correlation; the problem concerns the information retained by several such scores and their noise geometry. We develop an ordered-gap estimator with direction-specific concentration radii. Its finite-sample guarantee separates signature noise, missing groups, and candidate coverage, and allows the group count to grow under an attainable-margin condition. A coordinatewise partition followed by label-tuple refinement recovers groups even when every individual coordinate has population collisions. A binary-code construction explains why the one-dimensional inverse-group margin restriction need not govern a retained coordinate bank. We derive actual-law concentration from bounded ranking modules and a fixed-dimensional combinatorial central limit theorem under an observed permutation representation. A binary ordinal submodel gives logarithmic exact-recovery information scales. A subject-effect construction distinguishes persistent overlap from reducible measurement noise, and an additional ordinal anchor quantifies how new information lowers that error floor. Five focused simulation scenarios illustrate direction-specific calibration, growing-group recovery, coordinate collision resolution, variance reduction, and the effect of an additional ordinal anchor.

Adaptive Inference in Multivariate Nonparametric Regression Models Under Monotonicity

We consider the problem of adaptive inference on a regression function at a point under a multivariate nonparametric regression setting. The regression function belongs to a Hölder class and is assumed to be monotone with respect to some or all of the arguments. We derive the minimax rate of convergence for confidence intervals (CIs) that adapt to the underlying smoothness, and provide an adaptive inference procedure that obtains this minimax rate. When the regression function is monotone in $k_{+}$ of its $k$ arguments, the minimax expected length over a Hölder class with exponent $γ'$ of CIs that maintain coverage over a rougher class with exponent $γ$ is of order $n^{-1/(2+k_{+}/γ'+(k-k_{+})/γ)}$. The rate is unchanged if the rougher class restricts the smoothness only at the point, along the nonmonotone arguments. Under monotonicity along a closed convex cone that contains no line, only the dimension of its linear span enters the rate. The procedure differs from that of Cai and Low (2004), intended to yield shorter CIs under practically relevant specifications. It is valid in finite samples under Gaussian errors with a known variance. The proposed method applies to general linear functionals of the regression function.

Adaptive Bayesian Estimation of Conditional Densities Based on Orthogonal Polynomials

We study Bayesian estimation of conditional densities represented by normalized squares of orthogonal polynomial series. We specify the conditional density without modeling the marginal distribution of covariates. A prior on smoothness, the number of terms, and the coefficients gives adaptive posterior contraction at the minimax rate without a logarithmic factor when the normalized square-root representation of the true density is bounded away from zero and sufficiently smooth. For one outcome and $d_x$ covariates, the rate over classes with degree smoothness $s$ is $n^{-s/(2s+d_x+1)}$. The posterior predictive density attains the corresponding minimax squared Hellinger risk. For bounded nonnegative representations in Legendre and Chebyshev classes, we establish the minimax rate at every $s>0$. A prior that also permits a small mixture with the reference density adapts over these classes up to a logarithmic factor and retains the exact rate on the positive, sufficiently smooth subclass. Additional results concern identification, conditional distribution functions and quantiles, coefficient recovery and uniform convergence, independent Gaussian coefficient priors, and selection of polynomial terms.

On the median of the beta distribution in relation to the median of the gamma distribution

The median of the beta distribution has no closed form, but it is closely tied to the median of the gamma distribution. Kerman's approximation has the ratio form $g(α)/(g(α)+g(β))$ with $g(x) = x - 1/3$, a lower bound on the gamma median, and it is a lower bound on the beta median for $1/3 < α< β$. The ratio form built from the true gamma median is a tighter lower bound, asymptotically exact as $β\to \infty$. The ratio form built from the Wilson-Hilferty approximation to the gamma median, implicit in a classical approximation to the $F$ distribution but little known as an approximation to the beta median, is an upper bound on the edge $α= 1$ and for large shape parameters. The ratio form that is exact on the lines $α= 1$ and $β= 1$ yields a new approximation to the gamma median, which is an upper bound on it for shape parameter below 1 and a lower bound above 1; no ratio form gives the beta median exactly. For large shape parameters, the logit of the median has an explicit second-order expansion. For small shape parameters, bounds in elementary functions are asymptotically tight, and odds-corrected forms of the low-$α$ asymptote, with an elementary factor that is exact on the edges $α= 1$ and $β= 1$, are, numerically, one-sided bounds within 0.44% of the median that are exact on the lines $α= 1$, $β= 1$, and $α= β$. Steering their exponents with four fitted constants, and interpolating between two ratio forms where both shape parameters exceed 1, gives an approximation in elementary functions that is exact on those lines and numerically within 0.065% of the median over the whole domain. Most of the proofs are machine-verified in Lean 4.
