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…
Our approach used normalized band depths, calculated from continuum-removed reflectance spectra, coupled with stepwise multiple linear regression. Laboratory spectra of dry, ground leaves were used to establish the baseline validity of this Acknowledgements This research was supported by the NASA ...
