Estimates potential missing values, detects and determines outliers and
simultaneously fits an
model to the outlier free time series.

- d
- Type: SystemInt32
A non-negative scalar int, the order of the difference used in the model.
Exceptions Exception | Condition |
---|
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.
|
SingularTriangularMatrixException |
is thrown if the input matrix to ARAutoUnivariate is singular.
|
NonInvertibleException |
is thrown if the intermediate or final maximum likelihood estimates for
the time series are noninvertible.
|
NonStationaryException |
is thrown if the intermediate or final maximum likelihood estimates for
the time series are nonstationary.
|
InitialMAException |
is thrown if the initial values provided for the moving average terms are
noninvertible. In this case, ARMAMaxLikelihood terminates and does
not compute the time series estimates.
|
DidNotConvergeException |
is thrown if the algorithm computing the roots of the AR- or MA-
polynomial does not converge.
|
SingularMatrixException |
is thrown if during the computation of a small perturbation of the matrix
product , it is found that A, the matrix
used in the determination of the weights,
is singular.
|
NotSPDException |
is thrown if during the computation of
a small perturbation of the matrix product ,
it is found that A, the matrix used in the determination of the
weights, is not positive definite.
|
NoAcceptableModelFoundException |
is thrown if no appropriate ARIMA model for the given time series could be found.
