void ArMCovariance(TVec Src, Int32 Order, TVec A, ref Double E)
Modified covariance method for autoregressive parameter estimation.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TVec | source TVec |
| 2 | Order | Int32 | |
| 3 | A | TVec | source TVec |
| 4 | E | Double (ref) | output |
Result: stored in self (calling object)
Remarks:
The AR parameters are estimated by minimizing the average of the estimated forward and backward prediction error powers. Src contains the data on which the autoregressive parameter estimation (placed in A) should be based. Order defines the Order of the autoregressive process. E is the prediction error.
