(Normalized) root mean square error
Calculate the (normalized) root-mean-square-error of two vectors.
Arguments
- a, b
numeric vectors of same length to be compared
- normer
a character string defining the type of normalization to be applied. Can be one of
- mean
the arithmetic mean of a
- sd
the standard deviation of a (default).
- range
the difference between the range of a
- IQR
the difference between the interquantile range of a
