We investigate nonlinear regression and introduce a novel approach based on the joint optimization of linear models. In order to capture both characteristics in sequential data, we model underlying data as combination models, where optimize models jointly minimize final error. As model, employ differentiable version boosted decision trees. use well-known SARIMAX model. Our is generic so that an...

this research was investigated to analyze genotype × environment (ge) interaction for grain yield in durum wheat multi-environment trials (met) conducted in dryland agricultural research stations (dari) using gge (g + ge interaction) biplot methodology and joint regression analysis (b +  s2di). the environment, ge interaction and genotype effects were accounted for 84%, 7.7% and 2.3% of total s...

BACKGROUND Polytomous logistic regression models are commonly used in case-control studies of cancer to directly compare the risks associated with an exposure variable across multiple cancer subtypes. However, the validity, accuracy, and efficiency of this approach for prospective cohort studies have not been formally evaluated. METHODS We investigated the performance of the polytomous logist...

The aim of this paper was to examine finger and bow string movements during archery by investigating a top Austrian athlete (FITA score = 1233) under laboratory conditions. Maximum lateral bow string deflection and angular displacements for index, third, and ring fingers between the full draw position and the end of the release were quantified using a motion tracking system. Stepwise multiple r...

The aim of this study is to evaluate the effect of information delay on theperformance of joint investment funds. In order to achieve the aim of thisstudy sample consisted of twenty funds in the Tehran Stock Exchange from2010 to 2014 the systematic elimination method has been adopted. In thisstudy, the linear regression test has been used in order to evaluate the researchhypothesis. Data analys...

Correct estimation of water inflow into underground excavations can decrease safety risks and associated costs. Researchers have proposed different methods to asses this value. It has been proved that water transmissivity of a rock joint is a function of factors, such as normal stress, joint roughness and its size and water pressure therefore, a laboratory setup was proposed to quantitatively m...

The external knee adduction moment is considered a surrogate measure for the medial tibiofemoral contact force and is commonly used to quantify the load reducing effect of orthopedic interventions. However, only limited and controversial data exist about the correlation between adduction moment and medial force. The objective of this study was to examine whether the adduction moment is indeed a...
