The proposed estimator is super efficient in nature in the ...
1、简介 开发了一种新的元启发式算法——Newton-Raphson-Based优化器(NRBO)。NRBO受到Newton-Raphson方法的启发,它使用两个规则:Newton-Raphson搜索规则(NRSR)和Trap Avoidance算子(TAO)以及几组矩阵来探索整个搜索过程,以进一步探索最佳结果。NRSR使用Newton-Raphson方法来提高NRBO的探索能力,并提高收敛速度以达到改进...
牛顿法(Newton’s method)又称为牛顿-拉弗森法(Newton-Raphson method),是一种近似求解实数方程式的方法。(注:Joseph Raphson在1690年出版的《一般方程分析》中提出了后来被称为“牛顿-拉弗森法”的数学方法,牛顿于1671年写成的著作《流数法》中亦包括了这个方法,但该书在1736年才出版。) 之前的一篇博客中提到的二...

4.3.1 Newton–Raphson algorithm The NR algorithm is an iterative method for finding estimates for the parameters by minimizing −2 times a specific log-likelihood function. In applying this algorithm, both ML and REML log-likelihood functions can be used to estimate the variance components (Laird...
Newton-Raphson-Based Optimizer (NRBO) is a novel metaheuristic algorithm proposed in this paper, drawing inspiration from Newton-Raphson's approach. The NRBO leverages two key rules, namely the Newton-Raphson Search Rule (NRSR) and the TAO, along with multiple groups of matrices to ...
2.Finally,Newton-Raphson algorithm is used to calculate the value of the parameters.首先写出观测数据的边缘对数似然函数,然后用拟蒙特卡罗方法将函数中的积分写成求和的形式,接着利用Newton-Raphson算法计算参数的极大似然估计。 3.Newton-Raphson algorithm and CM algorithm were used,at the same time amended ...
