MAD {mosaic} | R Documentation |
All pairs mean and sum of absolute differences
Description
The functions compute the sum or mean of all pairwise absolute
differences. This differs from stats::mad()
, which computes
the median absolute difference of each value from the median of
all the values. See the ISIwithR
package (and the textbook it
accompanies) for examples using these functions in the context of
simulation-based inference.
Usage
MAD(x, ..., data = NULL, groups = NULL, na.rm = getOption("na.rm", FALSE))
SAD(x, ..., data = NULL, groups = NULL, na.rm = getOption("na.rm", FALSE))
Arguments
x |
a numeric vector or a formula. |
... |
additional arguments passed through to |
data |
a data frame in which to evaluate formulas (or bare names).
Note that the default is |
groups |
a grouping variable, typically a name of a variable in |
na.rm |
a logical indicating whether NAs should be removed before calculating. |
Value
the mean or sum of the absolute differences between each pair
of values in c(x,...)
.
