Returns the sample relative mean difference.
Syntax
RMD(X)
- X
- is the input data sample (one/two dimensional array of cells (e.g. rows or columns))
Remarks
- The time series may include missing values (e.g. #N/A, #VALUE!, #NUM!, empty cell), but they will not be included in the calculations.
- The relative mean difference is defined in terms of the mean difference as follows:
$$\mathrm{RMD}= \frac{\mathrm{MD}}{\bar{x}}$$
where:
- $\bar{x}$ is the sample mean (average) of the time series
- $\mathrm{MD}$ is the mean difference of the time series
- The RMD is also equal to twice the Gini coefficient.
