| int __stdcall NDK_SCALE | ( | double * | X, |
| size_t | N, | ||
| double | K | ||
| ) |
Returns an array of cells for the scaled time series.
- Returns
- status code of the operation
- Return values
-
NDK_SUCCESS Operation successful NDK_FAILED Operation unsuccessful. See Macros for full list.
- Parameters
-
[in,out] X is the univariate time series data (a one dimensional array). [in] N is the number of observations in X. [in] K is the scalar/multiplier value.
- Remarks
-
- The time series is homogeneous or equally spaced.
- The scale operator is described as: \[ \left[z_t\right] =\left[x_t\right] \times \alpha \] Where:
- \(\left[z_t\right]\) is the scaled time series.
- \(\left[x_t\right]\) is the first time series.
- \(\alpha\) is a constant value.
- The returned array has the same size and time order as the first input time series.
