How man
y levels are recorded in the current file?
Consider how many factor levels
are recorded in the current data. A level defines a group of cases that experienced
identical conditions. If there are multiple factors, the current data must be arranged
so tha
t the levels of the first factor are a primary index within which the levels of
subsequent factors cycle.
How many levels should be in the new file? Enter the number of levels for each index.
The v
alues for multiple index variables are always sequential numbers. The values
start at 1 and increment for each level. The first index increments the slowest, and the
last index increments the fastest.
