J. Annan | 1997In a realistic model of a biological system there is usually uncertainty in some of the model parameters. A conventional Monte Carlo simulation handles this situation by randomly choosing parameters at the start of the simulation (from specified[...]![]()

A. Cerioli | 1997In this paper we suggest two modified chi-squared tests of independence in 2 x 2 tables when the data are spatially autocorrelated. For this purpose, we first derive the asymptotic distribution of standard test statistics based on the sample cro[...]![]()

B. Cade ; J. Richards | 1996A permutation test based on proportionate reduction in sums of absolute deviations when passing from reduced to full parameter models is developed for testing hypotheses about least absolute deviation (LAD) estimates of conditional medians in li[...]
