Tool (R-script) for calculating van Multi-Species Indicators (MSI) and trends in MSIs.

Multi-Species Indicators (MSI) are biodiversity indicators that combine the population development of species into a single indicator. The MSI-tool calculates an MSI, confidence intervals for the MSIs and linear and flexible (smoothed) trends. The trends are classified in terms like “moderate increase”, “strong decrease” or “stable”. A number of additional analyses can be performed like testing for changepoints, comparison of trends before and after a changepoint and the calculation and testing of the total change in a time series.
