| ARMAMaxLikelihoodGetForecast Method |
Returns forecasts
Namespace: Imsl.Stat
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
SyntaxParameters
- nForecast
- Type: SystemInt32
An input int representing the number of requested forecasts beyond the last value in the series.
Return Value
Type: DoubleA double array containing the nForecast+BackwardOrigin forecasts. The first BackwardOrigin forecasts are one-step ahead forecasts for the last BackwardOrigin values in the series. The next nForecast values in the returned series are forecasts for the next values beyond the series.
Exceptions| Exception | Condition |
|---|---|
| NonStationaryException | is thrown if the final maximum likelihood estimates for the time series are nonstationary. |
| NonInvertibleException | is thrown if the final maximum likelihood estimates for the time series are noninvertible. |
| InitialMAException | is thrown if the initial values provided for the moving average terms using SetMA are noninvertible. In this case, ARMAMaxLikelihood terminates and does not compute the time series estimates. |
| MatrixSingularException | is thrown if the input matrix is singular. |
| TooManyCallsException | is thrown if the number of calls to the function has exceeded the maximum number of iterations times the number of moving average (MA) parameters + 1. |
| IncreaseErrRelException | is thrown if the bound for the relative error is too small. |
| NewInitialGuessException | is thrown if the iteration has not made good progress. |
| IllConditionedException | is thrown if the problem is ill-conditioned. |
| TooManyIterationsException | is thrown if the maximum number of iterations is exceeded. |
| TooManyFunctionEvaluationsException | is thrown if the maximum number of function evaluations is exceeded. |
| TooManyJacobianEvalException | is thrown if the maximum number of Jacobian evaluations is exceeded. |
