关于我的数据给出错误的错误记录'系统在计算上是奇异的？
[英]R mlogit on my data giving error 'system is computationally singular?
问题描述
Could anyone explains what is the error and how could I resolve it? 
谁能解释什么是错误，我该如何解决？
> C.m<-mlogit(choice~TotalAmount,data=C)
Error in solve.default(H, g[!fixed]) :
system is computationally singular: reciprocal condition number = 6.87101e-23

Something in your data is computationally singular eg some of the columns you are trying to do the regression on are correlated. 数据中的某些内容在computationally singular是computationally singular例如，您要对其进行回归的某些列是相关的。 Maybe you can remove some of the correlated columns and try again without them. 也许您可以删除一些相关的列，然后在没有它们的情况下重试。
