The Influence of Matrix Size on Statistical Properties of Co-Occurrence and Limiting Similarity Null Models
Fig 2
Type I error rates of the limiting similarity null models.
Each panel represents a different combination of randomization algorithm, metric and criterion for determining the significance of the null model: inclusive p-values (≤ or ≥), exclusive p-values (< or >), and SES. The colour of each cell indicates the proportion of the 10,000 null models that were significant for that combination of species by sites. Blue cells indicate lower type I error rates and red cells indicate higher type I error rates.
