Computes the minimum AIC and optimum values for s and d based upon the candidates provided in SInitial
and DInitial
, and computes the values for the transformed series, .
Warnings are printed if a row in SInitial
is skipped due to too many observations lost in the differenced series or if problems occurred computing the optimum AIC using the differenced series.
Exception Type | 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. |
NonStationaryException | is thrown if the final maximum likelihood estimates for the time series are nonstationary. |
SingularTriangularMatrixException | is thrown if the input triangular matrix is singular. |
