Hi all,
I am trying to run the mice package (for multiple imputation) on a
data frame that is 5174 x 100. When I run mice(frame), I get the
following response:
Error in solve.default(t(xobs) %*% xobs) :
Lapack routine dgesv: system is exactly singular
and execution stops.
I'm no expert at matrix algebra, so if someone could explain this to
me and what I can do to get around it, I'd be very appreciative.
Thanks.
Best,
-N.
