Ranta et al. propose a test for space-time clustering by generalizing Whittemore et al.'s test. However, I think this test is inappropriate judging by several important points discussed below.

We developed a test statistic based on an approach of Whittemore et a / . (1987) to detect space-time clustering for non-infectious diseases. We extended the spatial test of Whittemore et al. by deriving conditional probabilities for Poisson distributed random variables. To combine spatial and time
