- Parameters
-
[in] pData is the univariate time series data (a one dimensional array). [in] nSize is the number of observations in pData. [in,out] mean is the ARMA model mean (i.e. mu). [in,out] sigma is the standard deviation of the model's residuals/innovations. [in] nIntegral is the model's integration order. [in,out] phis are the parameters of the AR(p) component model (starting with the lowest lag). [in] p is the number of elements in phis (order of AR component) [in,out] thetas are the parameters of the MA(q) component model (starting with the lowest lag). [in] q is the number of elements in thetas (order of MA component) [in] retType is a switch to select the type of value returned: 1= Quick Guess, 2=Calibrated, 3= Std. Errors Order Description 1 Quick guess (non-optimal) of parameters values (default) 2 Calibrated (optimal) values for the model's parameters 3 Standard error of the parameters' values [in] maxIter is the maximum number of iterations used to calibrate the model. If missing or less than 100, the default maximum of 100 is assumed.
- Remarks
-
- The underlying model is described here.
- The time series is homogeneous or equally spaced
- The time series may include missing values (e.g. NaN) at either end.
