The '''`rmse`''' function calculates [[Statistics/Residuals|root mean squared errors]].

== Usage ==

To calculate the root mean squared errors between two vectors representing predictions ('forecasts') and actual values, try:

{{{
rmse(F,A)
}}}

To calculate the root mean squared errors between all elements in two same-sized matrices, try:

{{{
rmse(F,A,"all")
}}}

Note that this is effectively the same as calculating the [[MATLAB/Norm|Frobenius product]] as `norm(F-A,"fro")` and then dividing it by the square root of the number of elements. (Recall that it is root ''mean'' squared errors.)
