avg(group,value)
This computes the arithmetic mean of a value in a group. See avg_if() for a for a related conditional operator.
group describes the notes to be examined and may be any of {children,descendants,siblings,ancestors,all}.
value may be any valid expression, but will usually be a reference to an attribute; short form Boolean attribute expressions are acceptable.
For example:
avg(children(/Catalog),$Price)
returns the average price of all the items in Catalog.
