I've reimplemented EXAMINE and added a test for this bug.

The mean calculated by EXAMINE is different for the calculated by FREQUENCIES. Seems like EXAMINE doesn't ignore missing values, whilst FREQUENCIES do.

In the example above, I've created a simple data and ask for mean on both FREQUENCIES and EXAMINE. The result is different.

DATA LIST LIST /x.
BEGIN DATA.
1
9999999999
END DATA.

MISSING VALUES x (9999999999).

FREQUENCIES
  /VARIABLES= x
  /FORMAT=AVALUE TABLE
  /STATISTICS=MEAN.

EXAMINE
  /VARIABLES= x
  /STATISTICS=DESCRIPTIVES
  /MISSING=LISTWISE.
