IRREGULAR Statement
IRREGULAR name <option> ;
The IRREGULAR statement specifies a one-dimensional white noise component, which can be used to specify the observation error in a MODEL statement. The following option can be used in the IRREGULAR statement:
VARIANCE=variable | number

specifies the variance of the white noise. Any nonnegative value, including zero, is permissible. If the variable contains unknown parameters, they are estimated from the data. Similarly, if the VARIANCE= option is not specified, the variance is estimated from the data.


Note: This procedure is experimental.
