All the lists must have equal dimensions except

for

list5

list1

represents xlist.

list2

represents ylist.

list3

represents frequency.

list4

represents category codes.

list5

represents category include list.

iterations

specifies the maximum number of times

a solution will be attempted. If omitted, 64 is

used. Typically, larger values result in better

accuracy but longer execution times, and vice

versa.

Note:

list1

through

list4

must be a variable name

or c1–c99 (columns in the last data variable

shown in the Data/Matrix Editor).

list5

does not

have to be a variable name and cannot be c1–c99
