Logistic model for stock market bubbles and anti-bubbles [PDF]

open access: yes, 2017
Log-periodic power laws often occur as signatures of impending criticality of hierarchical systems in the physical sciences. It has been proposed that similar signatures may be apparent in the price evolution of financial markets as bubbles and the ...

Association testing to detect gene-gene interactions on sex chromosomes in trio data

open access: yesFrontiers in Genetics, 2013
Autism Spectrum Disorder (ASD) occurs more often among males than females in a 4:1 ratio. Among theories used to explain the causes of ASD, the X chromosome and the Y chromosome theories attribute ASD to X-linked mutation and the male-limited gene ...

Logistic regression models

open access: yesAllergologia et Immunopathologia, 2011
In the health sciences it is quite common to carry out studies designed to determine the influence of one or more variables upon a given response variable. When this response variable is numerical, simple or multiple regression techniques are used, depending on the case.

The use of the nonlinear models in the growth of pears of ‘Shinseiki’ cultivar

open access: yesCiência Rural, 2017
: The goal of this study was to elucidate the growth and development of the Asian pear fruit, on the grounds of length, diameter and fresh weight determined over time, using the non-linear Gompertz and Logistic models.

LMTRDA: Using logistic model tree to predict MiRNA-disease associations by fusing multi-source information of sequences and similarities

open access: yesPLoS Comput. Biol., 2019
Emerging evidence has shown microRNAs (miRNAs) play an important role in human disease research. Identifying potential association among them is significant for the development of pathology, diagnose and therapy. However, only a tiny portion of all miRNA-

Mathematical modelling of forecasting the results of knowledge testing / Žinių tikrinimo rezultatų prognozės matematinis modeliavimas

open access: yesTechnological and Economic Development of Economy, 2008
In this paper a mathematical model for obtaining probability distribution of the knowledge testing results is proposed. Differences and similarities of this model and Item Response Theory (IRT) logistic model are discussed.

Assessing the freshwater distribution of yellow eel

open access: yesKnowledge and Management of Aquatic Ecosystems, 2009
In the global context of the decline in wild species, modeling the distribution of populations is a crucial aspect of ecological management. This can be a major challenge, especially for species, such as the European eel, that have complex life cycles ...

Comparative analysis of phenomenological growth models applied to epidemic outbreaks

open access: yesMathematical Biosciences and Engineering, 2019
Phenomenological models are particularly useful for characterizing epidemic trajectories because they often offer a simple mathematical form defined through ordinary differential equations (ODEs) that in many cases can be solved explicitly.

High-dimensional Ising model selection using ${\ell_1}$-regularized logistic regression [PDF]

open access: yes, 2010
We consider the problem of estimating the graph associated with a binary Ising Markov random field. We describe a method based on $\ell_1$-regularized logistic regression, in which the neighborhood of any given node is estimated by performing logistic ...

Groundwater Potential Mapping Using an Integrated Ensemble of Three Bivariate Statistical Models with Random Forest and Logistic Model Tree Models

open access: yesWater, 2019
In the future, groundwater will be the major source of water for agriculture, drinking and food production as a result of global climate change. With increasing population growth, demand for groundwater has increased.
