      Or are we working with a new, global definition of

      All models have either an implicit or explicit error structure, where
      error is defined as the difference between the model prediction 
      and the "true" value.   Additionally, many data snooping methodologies 
      within the field of Statistics need to be applied to data supplied to
      a model.   Also, diagnostic checking, as defined within the field of 
      Statistics, is required for any model which uses data.  Thus all
      models which use data fall within the realm of the field of Statistics. 
      With this definition of "Statistics" the statement is true.
