int __stdcall NDK_RMD | ( | double * | X, |
size_t | N, | ||
WORD | reserved, | ||
double * | retVal | ||
) |
Returns the sample relative mean difference.
- Returns
- status code of the operation
- Return values
-
NDK_SUCCESS Operation successful NDK_FAILED Operation unsuccessful. See Macros for full list.
- Parameters
-
[in] X is the input data sample (a one/two dimensional array). [in] N is the number of observations in X. [in] reserved This parameter is reserved and must be 1. [out] retVal is the calculated value of this function.
- Remarks
- 1. The time series may include missing values (NaN), but they will not be included in the calculations.
- 2. The relative mean difference is defined in terms of the NDK_MD 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.
- 3: The RMD is also equal to twice the NDK_GINI.

- Parameters
-
[in] pData is the input data sample (a one/two dimensional array). [in] nSize is the number of observations in pData. [in] argMenthod This parameter is reserved and must be 1. [out] retVal is the calculated value of this function.

- 2. The relative mean difference is defined in terms of the NDK_MD 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.
