looking at first blush that I am looking at lots and lots of bell curves

This seems to me like a problem that must occur regularly in the DB2
world? There must already be paradigms for doing this? Any
experiences, pointers, or suggestions on ways to approach this?

This is an entire field of scholarly research.

I use the programming language R for this sort of analysis. My boss is
visual, and she sees patterns in graphs and charts that I can't.

Reaching in to DB2 uses JDBC.

drv <- JDBC("com.ibm.as400.access.AS400JDBCDriver",
"c:/buck/jt400/lib/jt400.jar", identifier.quote='"')
conn <- dbConnect(drv, "jdbc:as400:my.ibmi.com")
a <- dbReadTable(conn, "MYLIB.MYTABLE")
a <- dbGetQuery(conn, "select rlat, rlon, income from MYLIB.MYTABLE
where substr(rzip, 1, 3) = '021'")
