If you're combining more than one map, then the final RMSE will be the square root of the sum of the individual RMSEs, so if one high resolution map isn't behaving, but a lower res one is, then it may not be worth spending time getting the first one to fit any better. Correcting for bias often makes this worse: one can always choose a scale factor that performs better than the corrected sample variance, though the optimal scale factor depends on the excess kurtosis of the population (see mean squared error: variance), and introduces bias.
The most extensive description, based on a lost account by Aristobulus, who had accompanied Alexander of Macedon (q.v.) on his eastern campaign in the late 4th century B.C.E., is to be found in the Anabasis of Arrian (6.29), written in the 2nd century C.E.: -- The tomb: in the lower parts was built of stones cut square and was rectangular in form.

The Study of Root Mean Square (RMS) Value Mechanical, Electrical, Electronics Engineering INTRODUCTION The root mean square value of a quantity is the square root of the mean value of the squared values of the quantity taken over an interval. The RMS value of any function y=f(t) over the range t=a to t=b can be defined as: = − ∫ b a y dt b ...
Il valore RMSE (errore quadratico medio, Root Mean Squared Error) è una misura di errore assoluta in cui le deviazioni vengono elevate al quadrato per evitare che valori positivi e negativi possano annullarsi l'uno con l'altro. Con questa misura, inoltre, gli errori di valore maggiore vengono amplificati...

Suppose that the instantaneous value of the input voltage is measured by an ADC with a Full Scale Range of V fs volts, and a resolution of n bits. The real value can change through a range of q = Vfs / 2 n volts without a change in measured value occurring. The value of the measured signal is V m = V s - e, where

Root Mean Squared Error. What we need now is one overall measure of the rough size of the errors. You will recognize the approach to creating this The mean squared error of estimation is a measure of roughly how big the squared errors are, but as we have noted earlier, its units are hard to interpret.

Use this table to find the squares and square roots of numbers from 1 to 100.You can also use this table to estimate the square roots of larger numbers.For instance, if you want to find the square root of 2000, look in the middle column until you find the number that is closest to 2000.
So far as we are aware, no empirical investigations have examined choice of axes for funnel plots for continuous outcomes. For mean differences, the standard error is approximately proportional to the inverse of the square root of the number of participants, and therefore seems an uncontroversial choice for the vertical axis.

RMS Error. 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 To construct the r.m.s. error, you first need to determine the residuals. Residuals are the difference between the actual values and the predicted values.

A variance or standard deviation of zero indicates that all the values are identical. Variance is the mean of the squares of the deviations (i.e., difference in values from the mean), and the standard deviation is the square root of that variance. Standard deviation is used to identify outliers in the data.

An RMSE of 13 might actually great, it completely depends on how your target variable is scaled. For example, if your target variable was in the range [0,1e9], than an RMSE of 13 is spectacular. On the other hand, if your target is in the range [0,1], an RMSE of 0.5 is terrible.
