A. Yool | 1999Variability enters ecological systems at many different levels, from the differences between organisms and their individual life histories, to differences in the species composition of communities and changes in the external environment. Incorpo[...]![]()

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[...]![]()

We discuss optimal choice of the numbers of resamples in the two stages of the iterated bootstrap, when that technique is used to calibrate bootstrap confidence intervals. If the numbers of resamples in the first and second stages are denoted by[...]![]()

A. Monti | 1994This note proposes a test of goodness of fit for time series models based on the sum of the squared residual partial autocorrelations. The test statistic is asymptotically chi(2). Its small-sample performance is studied through a Monte Carlo exp[...]![]()

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[...]
