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 =
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!
