Function Description
Returns a summary of the input data applicable to a two
factor Analysis of Variance (with replication), given an input array, InputArray,
which needs to be of length n1 x n2, where n1 is the
number of groups of data and n2 is the number of observations for each
group, with the groups further subdivided into sub-groups, the (string) values
of which are contained in the array SubGroups.
The output is a numeric array with (m+1) x 4 rows and
n2 + 1 columns as follows (akin to that supplied by the Data Analysis
Toolpack available via Microsoft Excel), where m is the number of
distinct subgroups in the array SubGroups:
Each group of 4 rows contains summary data for a sub-group
(the last 4 rows containing summary data for all subgroups combined), in order
that the subgroup first appears in array SubGroups. Within each group of
4 rows the data is as follows:
Row 1: Count
Row 2: Sum
Row 3: Average
Row 4: Sample variance
Each column relates to a separate column within the input
