I want to know if this values is acceptable normalized root mean square error because as a percentage value =3.762*100 = 376.2% Is this possible as an error . I find this is not logic . Could you please help me how to understand theis percentage high value.

Description`Y`

` = rms(X)`

returns the root-mean-square (RMS) level of the input, X. If X is a row or column vector, Y is a real-valued scalar. For matrices, Y contains the RMS levels computed along the first nonsingleton dimension. For example, if X is an N-by-M matrix with N>1, Y is a 1-by-M row vector containing the RMS levels of the columns of X.`Y`

` = rms(X,DIM)`

computes the RMS level of X along the dimension, DIM.Input ArgumentsX Real or complex-valued input vector or matrix. By default, rms acts along the first nonsingleton dimension of X. DIM Dimension for RMS levels. The optional DIM input argument specifies the dimension along which to compute the RMS levels. Default: First nonsingleton dimensionOutput ArgumentsY Root-mean-square level. For vectors, Y is a real-valued scalar. For matrices, Y contains the RMS levels computed along the specified dimension DIM. By default, DIM is the first nonsingleton dimension. Examplescollapse allRMS Lev

to calculate the root mean square error. Assume you have one set of numbers that represent the Actual values you want to predict. Actual = [1 2 3 4]; Then assume you have another set of numbers that Predicted the actual values. Predicted = [1 3 1 4]; How do you evaluate how close Predicted values are to the Actual values? Well you could use the root mean square error (RMSE) to give a sense of the Predicted values error. Here's some MATLAB code that does exactly that. % rmse tutorial. % The actual values that we want to predict. Actual = [1 2 3 4]; % The values we actually predicted. Predicted = [1 3 1 4]; % One way is to use the Root Mean Square function and pass in the "error" part. rmse = rms(Predicted-Actual) % That's it! You're done. % But for those of you who are the curious type, % here's how to calculate the root-mean-square-error by hand. % First calculate the "error". err = Actual - Predicted; % Then "square" the "error". squareError = err.^2; % Then take the "mean" of the "square-error". meanSquareError = mean(squareError); % Then take the "root" of the "mean-square-error" to get % the root-mean-square-error! rootMeanSquareError = sqrt(meanSquareError) % That's it! You have calculated the RMSE by hand. % So, this is true. rootMeanSquareError == rmse Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Google+ (Opens in new window) Related Author JeremyPosted on July 10, 2013February 4, 2014Categories MATLAB 2 thoughts on “Root Mean Square Error tutorial - MATLAB” Pingback: Mean absolute error tutorial MATLAB | kawahara.ca Roman says: June 18, 2014 at 2:02 pm Thanks!
