logbin: An R Package for Relative Risk Regression Using the Log-Binomial Model

open access: yesJournal of Statistical Software, 2018
Relative risk regression using a log-link binomial generalized linear model (GLM) is an important tool for the analysis of binary outcomes. However, Fisher scoring, which is the standard method for fitting GLMs in statistical software, may have ...

SQUAREM: An R Package for Off-the-Shelf Acceleration of EM, MM and Other EM-Like Monotone Algorithms

open access: yesJournal of Statistical Software, 2020
We discuss the R package SQUAREM for accelerating iterative algorithms which exhibit slow, monotone convergence. These include the well-known expectation-maximization algorithm, majorize-minimize (MM), and other EM-like algorithms such as expectation ...

Statistical convergence of the EM algorithm on Gaussian mixture models [PDF]

open access: yesElectronic Journal of Statistics, 2018
We study the convergence behavior of the Expectation Maximization (EM) algorithm on Gaussian mixture models with an arbitrary number of mixture components and mixing weights. We show that as long as the means of the components are separated by at least $\

flexCWM: A Flexible Framework for Cluster-Weighted Models

open access: yesJournal of Statistical Software, 2018
Cluster-weighted models (CWMs) are mixtures of regression models with random covariates. However, besides having recently become rather popular in statistics and data mining, there is still a lack of support for CWMs within the most popular statistical ...

Statistical Generalized Derivative Applied to the Profile Likelihood Estimation in a Mixture of Semiparametric Models

open access: yesEntropy, 2020
There is a difficulty in finding an estimate of the standard error (SE) of the profile likelihood estimator in the joint model of longitudinal and survival data.

Determination of Load Equivalency Factors by Statistical Analysis of Weigh-In-Motion Data

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2016
The load equivalency factors for pavement design currently in use by the Hungarian standard have been developed using Weigh-in-Motion data obtained during the first few years of operations after installing some 30 measuring sites in Hungary in 1996.

Regression Analysis of Cure Model with Generalised Weibull Distribution

open access: yesStatistica, 2021
Cure models are of special attention when all of the study subjects do not experience the event of interest even after long follow-up time. Many researchers have used exponential, gamma and Weibull distribution in the latency part of parametric cure ...

A probabilistic analysis of a leader election algorithm [PDF]

open access: yes, 2006
A {\em leader election} algorithm is an elimination process that divides recursively into tow subgroups an initial group of n items, eliminates one subgroup and continues the procedure until a subgroup is of size 1.
