RMSE(Root mean square error) of the measurement. So, if we removing Systematic errors from a data set, what happen the RMSE (Root mean square error) value? It becomes smaller or larger? I am happy if any one answer my question.

@Hani: Since \(\text{RMSE} = \sqrt{\text{MSE}}\) with \(\text{MSE} = \text{Var} + \text{Bias}^2\) – the effect of eliminating the systematic error (bias) [kind of obviously] is: ___________? [P.S.: random errors, missing values, etc. are a 'different animal'.]
