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…
Fit a stepwise linear regression model to the data. Specify 0.06 as the threshold for the criterion to add a term to the model. mdl = stepwiselm(ingredients,heat,'PEnter',0.06) 1. Adding x4, FStat = 22.7985, pValue = 0.000576232 2. Adding x1, FStat = 108.2239, pValue = 1.105281e-06...
Simple linear regression model describes the relationship between heavy metals and one explanatory variable such as NDVI or REP. Although simple in structure, such univariate regression models are not so accurate, and have to be combined with other methods (e.g., principal component regression) to...
回归分析可以分为线性回归(linear regression)和非线性回归(nonlinear regression)。其中线性回归包括一元线性回归、多元线性回归。线性回归中比较特殊的回归分析有对数线性回归(Log-linear model)——是将自变量和因变量都取对数值之后再进行线性回归。非线性回归则包括逻辑回归(Logistic Regression)、偏回归(Partial Regressio...
