Analysis of criteria system model for construction contract evaluation

open access: yesTechnological and Economic Development of Economy, 2007
A number of multicriteria decisions must be made during construction investment processes. A number of support systems for multicriteria tasks of construction investment processes are available. Part of them is reviewed in this article.

Zero-Inflated Generalized Linear Mixed Models: A Better Way to Understand Data Relationships

open access: yesMathematics, 2021
Our article explores an underused mathematical analytical methodology in the social sciences. In addition to describing the method and its advantages, we extend a previously reported application of mixed models in a well-known database about corruption ...

Discriminating neutrino mass models using Type II seesaw formula

open access: yes, 2004
In this paper we propose a kind of natural selection which can discriminate the three possible neutrino mass models, namely the degenerate, inverted hierarchical and normal hierarchical models, using the framework of Type II seesaw formula.

Gene Function Classification Using Bayesian Models with Hierarchy-Based Priors [PDF]

open access: yes, 2006
We investigate the application of hierarchical classification schemes to the annotation of gene function based on several characteristics of protein sequences including phylogenic descriptors, sequence based attributes, and predicted secondary structure.

Yukawa Hierarchy Transfer from Superconformal Sector and Degenerate Sfermion Masses [PDF]

open access: yes, 2001
We propose a new type of supersymmetric models coupled to superconformal field theories (SCFT's), leading simultaneously to hierarchical Yukawa couplings and completely degenerate sfermion masses.

Mathematical modelling of tissue formation on the basis of ordinary differential equations

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
A mathematical model is proposed for describing the population dynamics of cellular clusters on the basis of systems of the first-order ordinary differential equations.

Evaluation of Risk Prediction with Hierarchical Data: Dependency Adjusted Confidence Intervals for the AUC

open access: yesStats, 2023
The area under the true ROC curve (AUC) is routinely used to determine how strongly a given model discriminates between the levels of a binary outcome. Standard inference with the AUC requires that outcomes be independent of each other.

Hierarchical Interaction Models

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1990
SUMMARY Lauritzen and Wermuth have proposed a class of models for mixed qualitative and continuous data, defined by two properties: that the continuous variables are normally distributed given the qualitative variables and that a set of conditional independence relations hold between specified pairs of variables.

Bayesian Hierarchical Random Effects Models in Forensic Science

open access: yesFrontiers in Genetics, 2018
Statistical modeling of the evaluation of evidence with the use of the likelihood ratio has a long history. It dates from the Dreyfus case at the end of the nineteenth century through the work at Bletchley Park in the Second World War to the present day.

Prior choice and data requirements of Bayesian multivariate hierarchical models fit to tag‐recovery data: The need for power analyses

open access: yesEcology and Evolution, 2023
Recent empirical studies have quantified correlation between survival and recovery by estimating these parameters as correlated random effects with hierarchical Bayesian multivariate models fit to tag‐recovery data.
