Methods in com.imsl.stat that throw ARMA.MatrixSingularException

Modifier and Type	Method and Description
void	ARSeasonalFit.compute() 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, $W_t(s,d)$.
void	ARAutoUnivariate.compute() Determines the autoregressive model with the minimum AIC by fitting autoregressive models from 0 to maxlag lags using the method of moments or an estimation method specified by the user through setEstimationMethod.
void	ARMA.compute() Computes least-square estimates of parameters for an ARMA model.
void	AutoARIMA.compute(int maxlag) Estimates potential missing values, detects and determines outliers and simultaneously fits an optimum model from a set of different $\text{ARIMA}(p,0,0)\times(0,d,0)_s$ models to the outlier free time series.
void	ARMAOutlierIdentification.compute(int[] model) Detects and determines outliers and simultaneously estimates the model parameters for the given time series.
void	AutoARIMA.compute(int[] arOrders, int[] maOrders) Estimates potential missing values, detects and determines outliers and simultaneously fits an optimum model from a set of different $\text{ARIMA}(p,0,q)\times(0,d,0)_s$ models to the outlier free time series.
