An exact formula for the mean squared error of the inverse estimator, involving expectations of functions of a Poisson random variable, is derived. The formula may be expressed in closed form if the number of observations in the calibration experiment is odd; for an even number of observations,...
Root mean square is the square root of a mean square of a group of values. Learn how to calculate the RMS using the formula and example along with the RMS Error (RMSE) by visiting BYJU'S.
Root Mean Square Error Formula The RMSE of a model with respect to the estimated variable xmodel is defined as the square root of the mean squared error. RMSE=∑ni=1(Xobs,i−Xmodel,i)2n−−−−−−−−−−−−−√RMSE=∑i=1n(Xobs,i−Xmodel,i)2n Where...

The square root of any number is equal to a number, which when squared gives the original number. Let us say m is a positive integer, such that √(m.m) = √(m2) = m In mathematics, a square root function is defined as a one-to-one function that takes a positive number as an ...
