value, it appears at the bottom of the value list. The order of the values is important;
it corresponds to the ascending order of the category values of the test variable.
The first v
alue of the list corresponds to the lowest group value of the test variable,
and the last value corresponds to the highest value. Elements of the value list are
summed, and then each value is divided by this sum to calculate the proportion of
cases expe
cted in the corresponding category. For example, a value list of 3, 4, 5, 4
specifies expected proportions of 3/16, 4/16, 5/16, and 4/16.
