黄土拟合和结果方程 [英] Loess Fit and Resulting Equation

问题描述

我是俄勒冈州波特兰市的一名开发商.我想知道是否有人可以提供帮助:

I'm a developer up in Portland, OR. I'm wondering if anyone can assist:

一旦有了合适的拟合度，我就会使用R进行黄土拟合模型 完成了，我正在寻找支持的方程式 拟合非线性曲线，想知道是否有办法 在R中确定这个方程?我一直在寻找但找不到 任何文学.对我来说，函数的图形很棒，但是 没有图表的方程式，我有点沉迷于水中.

I'm working on Loess fit models using R, once I have the fit accomplished, I'm looking to back-out the equation of the fitted non-linear curve, wondering if there is a way to determine this equation in R? I've been looking but can't find any literature. For me, the graph of the function is great, but without the equation of the graph, I'm kinda dead in the water.

推荐答案

黄土没有给您一个等式[1].如果只想获取黄土函数返回的值，请使用predict(loess.object, new.data)

Loess doesn't give you an equation [1]. If you just want to get the values returned by the loess function you use predict(loess.object, new.data)

[1] From wikipedia:

黄土的另一个缺点是 它不会产生一个事实 回归函数很容易 用数学公式表示. 这可能使转移变得困难 对其他人的分析结果 人们.为了转移 对另一个人的回归功能， 他们将需要数据集和 LOESS计算软件.

Another disadvantage of LOESS is the fact that it does not produce a regression function that is easily represented by a mathematical formula. This can make it difficult to transfer the results of an analysis to other people. In order to transfer the regression function to another person, they would need the data set and software for LOESS calculations.
