最近写了一个质谱的数据处理软件,其中一部分功能要实现实时线性拟合,并且求得拟合方程 R2、SD 、 pearson 系数以及进行统计学F检验求得p-value。 C#的自身库 以及开源库 Math.net 可以计算拟合方程 R2、SD 、 pearson 系数,但是并不能进行FTest检验。因此这里引用了R语言的类库 R.net,通过C#调用R语言实现这一...
aR squared coefficient is high, confirming that the regression model describes a large proportion of the variability of response. For each position the regression is also significant according to F test criterion for significance of R被摆正的系数高,证实回归模型描述反应的可变性的一个大比例。 为每个...
希望美赛的出题人可以给每一道题都提供数据,并且少做一些数据预处理工作。毕竟这个比赛本质上是数学建模竞赛,不是数据挖掘竞赛/数据预处理竞赛。 有一些题目的数据还涉及敏感数据,大多数学生是无法真的去获取这些数据的。 发布于 2024-02-03 09:11・IP 属地山东 AI 总结 如何评价2024美赛A-F题? 已引用 ...
