simboot (Q31134)

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 to choose. 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 while simultaneously testing a user-defined selection of Hill numbers of orders q, which are considered as appropriate and useful indices for measuring diversity.
