TS 1 The number of orders in a time-series model is wrong.

TS 2 An order in a time-series model is invalid.

TS 3 The number of parameters in a time-series model is wrong.

TS 4 A parameter in a time-series model is invalid.

TS 5 A group of parameters in a time-series model are invalid.

TS 6 The number of lags in a time-series model is wrong.

TS 7 A lag in a time-series model is invalid.

TS 8 A time-series model is of the wrong type (arima or transfer-function).

TS 9 The autocorrelation function is not positive definite.

TS 10 A time-series model is non-stationary.

TS 11 The maximum lag has not been defined.

TS 12 A value of the imaginary part of a sequence is invalid: set to zero.

TS 13 Invalid restriction for time series: units must be contiguous.

TS 14 Solution of equations has failed in calculation of filtered series.

TS 15 Preliminary estimation has not been completed.

TS 16 Marginal likelihood is not defined: `LIKELIHOOD`

option reset to `EXACT`

.

TS 17 Transformation cannot be applied due to negative values.

TS 18 The setting of the `FIX`

option has the wrong number of values.

TS 19 There are no residual degrees of freedom.

TS 20 The iterative estimation process has failed to progress towards a solution.

TS 21 The iterative estimation process has not converged.

TS 22 `TDISPLAY`

, `TKEEP`

, and `TFORECAST`

must be preceded by an `TFIT`

statement.

TS 23 If set, the `OUTPUTSERIES`

parameter must supply the output series identifier.

TS 24 Future values of all input series must be supplied in `TFORECAST`

.

TS 25 Origin of updated forecast is less than origin of previous forecast.

TS 26 Maximum lead time undefined or invalid.

TS 27 An input series contains missing values: forecasts cannot be produced.

TS 28 The `FORECAST`

variate must have values set in units 1…`ORIGIN`

if `ORIGIN`

>0.

TS 29 Invalid ARIMA model for input series: will not be used to calculate SEs.

TS 30 `FUTURE`

variates have less than `ORIGIN+MAXLEAD`

values: cannot form forecasts.

TS 31 `NEWOBSERVATION`

variate must be set when `ORIGIN`

> 0.
