Details nrmse = 100 \frac {√{ \frac{1}{N} ∑_{i=1}^N { ≤ft( S_i - O_i \right)^2 } } } {nval} nrmse = 100 * [ rmse(sim, obs) / nval ] ; nval= range(obs, In GIS, the RMSD is one measure used to assess the accuracy of spatial analysis and remote sensing.

The RMSD of predicted values y ^ t {\displaystyle {\hat {y}}_{t}} for times t of a regression's dependent variable y t {\displaystyle y_{t}} is computed for n different predictions as the Squaring the residuals, taking the average then the root to compute the r.m.s. error, you first need to determine the residuals. Although the LR model is giving negative prediction values for several test data points, its RMSE is low compared to KNN. https://en.wikipedia.org/wiki/Root-mean-square_deviation

Accepts estimate and parameter values, as well as estimate values which are in deviation form.

In economics, the RMSD is used to determine whether an economic model fits economic indicators. Mean Square Error Formula I find this is not logic .

In many cases, especially for smaller samples, the sample range is likely to be affected by the size of sample which would hamper comparisons.

Coefficient of Determination0When correlation coefficient's value rises, error rises as well. http://themedemo.net/mean-square/normalized-mean-square-error.html Watch lists Setting up watch lists allows you to be notified of updates made to postings selected by author, thread, or any search variable. When normalising by the mean value of the measurements, the term coefficient of variation of the RMSD, CV(RMSD) may be used to avoid ambiguity.[3] This is analogous to the coefficient of Statisticians and non-statisticians should find it relatively easy to think in terms of RMSE of 3.4 metres or 5.6 grammes or 7.8 as a count.
