各位大侠你们好!我想请问一个sas统计模型问题,我在国外杂志投了一篇文章,现在修改意见回来。让我描述一下统计模型(the statistical design and model used in the analysis should be described in detail) 我试验这样设计,研究一种添加剂M对猪生产性能影响,设立4个组,A对照组,B对照组+100mg添加剂,C对照组+200mg添加剂,D对照组+300mg添加剂 结果如下: A B C D sem p值 Linear quadratic 生产性能 4.81 11.61 19.40 26.70 2.481 0.000 0.001 现在问题是我该怎么描述我的统计模型,也就是怎么回答the statistical design and model used in the analysis should be described in detail,谢谢大家!如果这样说行么(The nature of response to incremental additions of M was analyzed by polynomial contrasts. The model included linear and quadratic contrasts for effects of supplemental M.是不是太简单了?
