Custom Tables in SPSS Statistics prints several univariate statistics but these do not include the trimmed mean or the trimean. The trimmed mean is available in the EXAMINE procedure.
I would like to add the trimmed mean (as in Examine) and the trimean to the univariate statistics printed for scale variables by Custom Tables.
The trimean is defined in Tukey (1977, p. 46) as
(lower hinge + 2*median + upper hinge)/4
