Using spline functions (segmented polynomials) in regression models requires the knowledge of the location of the knots. Knots are the points at which independent linear segments are connected. Optimal positions of knots for linear splines of different orders were determined in this study for different scenarios, using existing estimates of covariance functions and an optimization algorithm. Th...
background : in medical studies, when the joint prediction about occurrence of two events should be anticipated, a statistical bivariate model is used. due to the limitations of usual statistical models, other methods such as artificial neural network (ann) and hybrid models could be used. in this paper, we propose a hybrid artificial neural network-genetic algorithm (ann-ga) model to predictio...
Improvement of one trait on its own will affect the performance of other traits because ofgenotypic correlations between traits. Index selection is one of the tools used by plant breedersto overcome this problem. The purpose of this paper is to evaluate selection indices developedfor improving grain yield in rice (Oryza sativa L.). Forty-nine rice genotypes were cultivated atTonekabon Rice Rese...
In this study, a bi-objective model for integrated planning of production-distribution in a multi-level supply chain network with multiple product types and multi time periods is presented. The supply chain network including manufacturers, distribution centers, retailers and final customers is proposed. The proposed model minimizes the total supply chain costs and transforming time of products ...
Abstract Artificial intelligence has had varying degrees of impact on various industries, and many traditional financial tasks have been replaced by artificial robots, which will inevitably lead to the transformation accounting management accounting, is also key continuous development enterprises. Firstly, this paper proposes a multiple linear regression algorithm, solved classical least square...
PURPOSE The genes for cytochrome P450 2C9 (CYP2C9) and vitamin K epoxide reductase complex subunit 1 (VKORC1) have been identified as important genetic determinants of warfarin dosing and have been studied. We developed warfarin algorithm for Korean patients with stroke and compared the accuracy of warfarin dose prediction algorithms based on the pharmacogenetics. MATERIALS AND METHODS A tota...
