WebMar 12, 2024 · 最小二乘估计是一种常用的参数估计方法,其特点包括:1)能够得到最优的估计结果,即使数据存在噪声或误差;2)能够处理多元线性回归问题;3)能够通过计算残差平方和来评估模型的拟合程度;4)能够通过计算标准误差来评估估计值的精度。 WebDec 1, 2011 · The method which requires the fewest function calls and is therefore often the fastest method to minimize functions of many variables is fmin_ncg. This method is a modified Newton’s method and uses a conjugate gradient algorithm to (approximately) invert the local Hessian.
