当使用S-plots从PLS-DA或OPLS-DA模型中筛选 p 值小于 0.05 的变量时,可以遵循以下的一些步骤: 1.建立模型: 首先,需要在适当的统计软件或编程环境(如 R、MATLAB 或 Python)中完成 PLS-DA 或 OPLS-DA 分析。 2.生成S-plot: 使用分析工具,基于已建立的模型生成 S-plot。该图展示了变量的协方差和相关性系数...
先将变量标准化：egen z1 = std(x1)…… 进行主成分分析：pca x*, mineigen(1) 主成分载荷分析：estat loading,cnorm(eigen) 效果分析：estat kmo（一般要大于0.7才适合做主成分分析） 碎石图：screeplot 主成分选择，一般选择前几个方差解释累计。
