推荐答案

数据中的某些内容是computationally singular例如您尝试对其进行回归的某些列是相关的. 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.

Something in your data is computationally singular e.g. some of the columns you are trying to do the regression on are correlated. Maybe you can remove some of the correlated columns and try again without them.
