> imp<-mice(mydataframe, seed=1) When trying the above command, I got the error term:
iter imp variable 1 1 medu Error in solve.default(xtx + diag(pen)) : system is computationally singular: reciprocal condition number = 1.16487e-025/ What does that mean? How can I address this issue? My dataframe has 257 observations for 99 variables. Could this be the origin of the problem? Could anyone helps me out? Thank you!
