: hmm, lsfit could be used to verify our answer.
: btw, when I run the dataset "space_ga",
: I got the following statement,
: 错误在solve.default(lhs) : 系统计算上是独特的: 互反条件数=6.78798e-020
: But "lhs" is invertible (lhs is square and det(lhs)!=0)
: what's wrong here?
hi dear pal~
did you try this data set in lsfit?
what if it works in lsfit....
