AMENDMENTS AND CORRECTIONS
Nathan Mantel has noted that the paper incorrectly states that
the Ederer-Myers-Mantel test (
Biometrics (1964), 20, 626638)
requires towns of equal population size. In fact, by conditioning
on the total number of leukaemias per town (per five-year period)
Ederer et al. avoid dealing with population size. Instead their
test requires only that town sizes do not change from year to
year within a five-year period. we apologize to these authors
for misrepresenting their results.
