# NDK_AIRLINE_SIM

 int __stdcall NDK_AIRLINE_SIM ( double * pData, size_t nSize, double mean, double sigma, WORD S, double theta, double theta2, UINT nSeed, double * retArray, size_t nSteps )

Returns an array of cells for the simulated values.

Returns
status code of the operation
Return values
 NDK_SUCCESS Operation successful NDK_FAILED Operation unsuccessful. See Macros for full list.
Parameters
 [in] pData is a univariate time series of the initial values (a one dimensional array). [in] nSize is the number of observations in pData. [in] mean is the model mean (i.e. mu). [in] sigma is the standard deviation of the model's residuals/innovations. [in] S is the length of seasonality (expressed in terms of lags, where s > 1). [in] theta is the coefficient of first-lagged innovation (see model description). [in] theta2 is the coefficient of s-lagged innovation (see model description). [in] nSeed is an unsigned integer for setting up the random number generators [out] retArray is the calculated simulation value [in] nSteps is the number of future steps to simulate for.
Remarks
1. The underlying model is described here.
2. The time series is homogeneous or equally spaced
3. The time series may include missing values (e.g. NaN) at either end.
4. NDK_ARMA_SIM returns an array of one simulation path starting from the end of the input data.
5. The input data argument (i.e. latest observations) is optional. If ommitted, an array of zeroes is assumed.
6. The time series is homogeneous or equally spaced.
7. The time series may include missing values (e.g. NaN) at either end.
8. The long-run mean argument (mean) can take any value or be omitted, in which case a zero value is assumed.
9. The value of the residuals/innovations standard deviation (sigma) must be positive.
10. The season length must be greater than one.
11. The input argument for the non-seasonal MA parameter - theta - is optional and can be omitted, in which case no non-seasonal MA component is included.
12. The input argument for the seasonal MA parameter - theta2 - is optional and can be omitted, in which case no seasonal MA component is included.
