Paper Details

Some researchers have used the following method to perform tests of association in two-way tables. Instead of using the original observation weights wk , define

Where n is the number of observation units in the sample. The sum of the new weights
w?k , then, is n. The ?observed? count for cell (i, j) is
xij = sum of the w? k ?s for observations in cell (i, j)
and the ?expected? count for cell (i, j) is m? ij = (xi+x+j)/n. Then compare the test statistic
to a ?2 (r?1) (c?1) distribution.
Does this test give correct p-values for data from a complex survey? Why, or why not?
