OBS Subcommand (FIT command)

OBS specifies the observed series to use for calculating the mean percentage error and mean absolute percentage error.

• OBS can be used only when the residual series are explicitly specified.
• The number and order of observed series must be the same as that of the residual series.
• If more than one residual series was calculated from a single observed series, the observed series is specified once for each residual series that is based on it.

Example

FIT ERRORS=ERR#1 ERR#2
  /OBS=VAR1 VAR1. 

• This command requests FIT statistics for two residual series, ERR#1 and ERR#2, which were computed from the same observed series, VAR1.
