Calculates the logistic regression and updates all
the system statistics variables.
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
.
