用到的包:MASS 提前需要明确一个问题: R和SPSS的回归结果不一定是一致的。因为R逐步回归是基于AIC指标的,而SPSS基于p值或F值。根据AIC准则,AIC值越小表明模型拟合效果越好。R逐步回归主要分为两步 第一步:lm…
backward stepwise regression,全部引入,然后一个一个的减;缺点:1.共线性; mixed stepwise Diagnostics方法,如何确定我们的基本假设是对的,假设都不对,建模就是扯淡;(Checking Linear Regression Assumptions in R | R Tutorial 5.2 | MarinStatsLectures,讲得比较透彻) residuals influence or leverage 我们一开始会检...
Normalized band depths were analyzed by a multiple stepwise linear regression algorithm to select wavelengths highly correlated with leaf nitrogen, lignin, and cellulose concentrations. The absorption bands used, the continuum end points, and the analysis were constrained to be applicable to remotely sens...

Stepwise Regression Stepwise regression is a method of regression modeling in which the choice of predictive variables is carried out by an automatic procedure. Learning Objectives Evaluate and criticize stepwise regression approaches that automatically choose predictive variables. Key Takeaways Key Points ...
If you need to investigate a fitted regression model further, create a linear regression model object LinearModel by using fitlm or stepwiselm. A LinearModel object provides more features than regress. Use the properties of LinearModel to investigate a fitted linear regression model. The object ...
