Lets you specify output and options for producing species accumulation and rarefaction curves.
Display
| Summary | For species accumulation methods the species richness and variance. For rarefaction the expected species richness, variance and confidence limits. |
Random method
Use these options to control settings for the random method.
| Number of permutations | The number of permutations used for the random method. |
| Seed | Specifies the seed to use for the sub-sampling without replacement. The default value of zero continues an existing sequence of random numbers or, if the generator has not yet been used in this run of Genstat, initializes the generator automatically. |
Rarefaction
These options can be used to control settings for the rarefaction curve.
| Step between sample sizes | This value specifies a step between sample sizes for which the expected number of species is calculated. |
| Confidence limit (%) | Lets you control the confidence limit for the rarefaction curve. The limit is expressed as a percentage and must be in the range 0-100. |
