Contrasting Diversity Values: Statistical Inferences Based on Overlapping Confidence Intervals

  title={Contrasting Diversity Values: Statistical Inferences Based on Overlapping Confidence Intervals},
  author={Ian Macgregor-Fors and Mark Edward Payton},
  booktitle={PloS one},
Ecologists often contrast diversity (species richness and abundances) using tests for comparing means or indices. However, many popular software applications do not support performing standard inferential statistics for estimates of species richness and/or density. In this study we simulated the behavior of asymmetric log-normal confidence intervals and determined an interval level that mimics statistical tests with P(α) = 0.05 when confidence intervals from two distributions do not overlap… CONTINUE READING
