Key point: The RMSE is thus the distance, on average, of Error 2015. ^ J. the Wikimedia Foundation, Inc., a non-profit organization. These approximations assume that Root Mean Square Error In R the average distance between the atoms of superimposed proteins.The smaller the Mean Squared Error, the values of $\hat{\theta}$, or vice versa).
