Ah! I think the tutorial was not updated when the LinearRegression API changed. Try changing the line arma::vec responses; to arma::rowvec responses; And then it will need to be filled differently: responses << 1.0 << 2.0 << 3.0 << 4.0 << 5.0; (Instead of the several lines that each end with arma::endr.) If that fixes your problem, I'll update the tutorials. Sorry for the error! -- Ryan Curtin | "You got to stick with your principles."
