simboot (version 0.2-0)

simboot-package: Simultaneous inference for diversity indices.

Description

Package simboot provides estimation of simultaneous bootstrap and asymptotic confidence intervals for diversity indices, namely the Shannon and the Simpson index. Several pre-specified multiple-comparison types are available. Further user-defined contrast matrices are applicable. In addition, simboot estimates adjusted as well as unadjusted $p$--values for two of the three proposed bootstrap methods. Further simboot allows for comparing biological diversities of two or more groups with simultaneously testing a user-defined selection of Hill numbers of orders q, which are considered appropriate and useful indices for measuring diversity.
