Compute the mean absolute deviation about the mean
ds_mdev(data, x = NULL)
| data | A numeric vector or |
|---|---|
| x | Column in |
The ds_mdev function computes the mean absolute deviation
about the mean. It is different from mad in stats package as
the statistic used to compute the deviations is not median but
mean. Any NA values are stripped from x before computation
takes place
