    Required
      term                   Anova term being tested

Description

    testalterr computes anova F-ratio using arbitrary numeric error term.  Used in those cases in which you know the numeric value of the
    error term but it does not exist a term in the current model.  It is useful for tests of simple interactions and simple main effects.

Examples

    You wish to compute the F-ratio for b*c using the residual values from an a larger model that is not currently in memory.

        . testalterr b*c, dfr(12) rss(16)
