摘要:

Previous work by Gentleman and Wilk on outliers in two-way tables is summarized, and their statisticQKis discussed. Instead of a plot ofQKvalues, we propose a two-stage test for the presence of two outliers or one outlier. Percentage points for the test statistics are estimated by Monte Carlo generations, and approximations to the percentage points are suggested. The 8 × 12 case is examined in detail and extensions to other cases are briefly discussed.
