We combine the k㎞earest Neighbors (kNN) method to the local linear estimation (LLE) approach to construct a new estimator (LLE﹌NN) of the regression operator when the regressor is of functional type and the response variable is a scalar but observed with some missing at random (MAR) ...
The quality of a linear regression fit is typically assessed using 2 related quantities: RSE and the R square i.RSE 表示为拟合值与被解释变量样本值平均相差RSE单位。 或者说,即使真实f和回归模型相等(函数形式,估计参数均相等),据此回归模型作出的预测值与真实值平均相差RSE个单位。 预测错误率=RSE/mean...

Given a value for K and a prediction point x0, KNN regression first identifies the K training observations that are closest to x0, represented by N0: \hat{f(x_0)} = \frac{1}{K}\sum_{x_i\in N_0}^{}{y_i} two KNN fits on a data set with p = 2 predictors.The fit with ...
This paper explores the impact of additive manufacturing processes on the properties of stainless steel SS404L, with a focus on the influence of printing parameters such as power, scanning speed, and deposition height on the material's final mechanical properties. The study emphasizes these factors...
