Root mean square error

The root - mean - square deviation (RMSD) or root - mean - square error (RMSE) is a frequently used measure of the differences between values (sample or population values) predicted by a model or an estimator and the values observed. RMSD is the square root of the average of squared errors. In other words, it tells you how concentrated the data is around the line of best fit.

The regression line predicts the average y value associated with a given x value. Note that is also necessary to get a measure of the spread of. Formally it is defined as.

The use of RMSE is very common, and it is considered an. That is probably the most easily. RMSE measures the differences between values. The ratio of the mean of square root of residuals squared to the mean of observed.

The root mean squared error (RMSE) Ei of an individual model i is evaluated by the equation: where P(ij) is the value predicted by the. A measure of the difference between locations that are known and locations.
