TSS is an index of the goodness-of- fit allowing to assess a how much a continuous variable simulated by any model fit presence/absence data, details can be found in Allouche et al, 2006. It allows to translate a map of any continuous variable into a map of presence/absence for a given set of spatial simulations. This is made possible by finding the threshold value of the continuous variable.
The TSS function loops over a wide range of threshold values and returns indicator values, which can be used to identify the most suitable threshold value.
