Effective Bi-immunity and Randomness [PDF]

open access: yes, 2016
We study the relationship between randomness and effective bi-immunity. Greenberg and Miller have shown that for any oracle X, there are arbitrarily slow-growing DNR functions relative to X that compute no ML random set. We show that the same holds when ML randomness is replaced with effective bi-immunity.

A New Zero-Inflated Negative Binomial Multilevel Model for Forecasting the Demand of Disaster Relief Supplies in the State of Sao Paulo, Brazil

open access: yesMathematics, 2022
This article presents the results of the implementation of a forecasting model, to predict the relief materials needed for assisting in decisions prior to natural disasters, thus filling a gap in the exploration of Generalized Linear Mixed Models (GLMM ...

On random-effects meta-analysis [PDF]

open access: yesBiometrika, 2015
Meta-analysis is widely used to compare and combine the results of multiple independent studies. To account for between-study heterogeneity, investigators often employ random-effects models, under which the effect sizes of interest are assumed to follow a normal distribution.

Misspecification in Generalized Linear Mixed Models and Its Impact on the Statistical Wald Test

open access: yesApplied Sciences, 2023
Generalized linear mixed models are commonly used in repeated measurement studies and account for the dependence between observations obtained from the same experimental unit.

The effect of splitting on random forests [PDF]

open access: yesMachine Learning, 2014
The effect of a splitting rule on random forests (RF) is systematically studied for regression and classification problems. A class of weighted splitting rules, which includes as special cases CART weighted variance splitting and Gini index splitting, are studied in detail and shown to possess a unique adaptive property to signal and noise. We show for

The effect of random-effects misspecification on classification accuracy [PDF]

open access: yesThe International Journal of Biostatistics, 2021
Abstract Mixed models are a useful way of analysing longitudinal data. Random effects terms allow modelling of patient specific deviations from the overall trend over time. Correlation between repeated measurements are captured by specifying a joint distribution for all random effects in a model.

Statistical Inference of Wiener Constant-Stress Accelerated Degradation Model with Random Effects

open access: yesMathematics, 2022
In the field of reliability analysis, the constant-stress accelerated degradation test is one of the most commonly used methods to evaluate a product’s reliability as degradation data are provided. In this paper, a constant-stress accelerated degradation

Effective aspects of Bernoulli randomness [PDF]

open access: yesJournal of Logic and Computation, 2019
AbstractIn this paper, we study Bernoulli random sequences, i.e. sequences that are Martin-Löf random with respect to a Bernoulli measure $\mu _p$ for some $p\in [0,1]$, where we allow for the possibility that $p$ is noncomputable. We focus in particular on the case in which the underlying Bernoulli parameter $p$ is proper (i.e.

On Fitting Generalized Linear Mixed Effects Models for Longitudinal Binary Data Using Different Correlation Structures

open access: yesRevstat Statistical Journal, 2018
The generalized linear mixed effects model (GLMM) approach is widely used to analyze longitudinal binary data when the goal of the study is a subject-specific interpretation because it allows missing values on the response, provided they are missing at ...
