Sharp bounds for stochastic proximal and projection estimators via radial dominance
Gonzalo Contador, Pedro Pérez-Aros, Emilio Vilches
We study stochastic barycentric estimators for proximal points and metric projections obtained by exponentially reweighting Gaussian perturbations. Our main result is an abstract c…
Optimal Adjustment and Combination of Independent Discrete -Values
Gonzalo Contador, Zheyang Wu
Combining p-values from multiple independent tests is a fundamental task in statistical inference, but presents unique challenges when the p-values are discrete. We extend a recent…
Differentiability and Approximation of Probability Functions under Gaussian Mixture Models
Gonzalo Contador, Pedro Pérez-Aros, Emilio Vilches
In this work, we study probability functions associated with Gaussian mixture models. Our primary focus is on extending the use of spherical radial decomposition for multivariate G…
Another reason why normalized gain should continue to be used to analyze concept inventories (and estimate learning rates)
Jairo Navarrete, Valentina Giaconi, Gonzalo Contador +1
A transformation called normalized gain (ngain) has been acknowledged as one of the most common measures of knowledge growth in pretest-posttest contexts in physics education resea…
A minimum Wasserstein distance approach to Fisher's combination of independent discrete p-values
Gonzalo Contador, Zheyang Wu
This paper introduces a comprehensive framework to adjust a discrete test statistic for improving its hypothesis testing procedure. The adjustment minimizes the Wasserstein distanc…
Sampling distributions and estimation for multi-type Branching Processes
Gonzalo Contador, Bret Hanlon
Consider a multi-dimensional supercritical branching process with offspring distribution in a parametric family. Here, each vector coordinate corresponds to the number of offspring…
