Habfuzz

Input 1 - A training dataset (multiple observations) of up to four variables (predictors) against one (response variable)
Input 2 - A test dataset (multiple observations) of the same four variables with unknown response variable
Output - Calculation of the response variable for each test observation using fuzzy logic or fuzzy rule-based Bayesian algorithms

HABFUZZ is a habitat model, which can be used in ecohydraulic modelling applications for the calculation of the instream habitat suitability in various discharge scenarios in a simulated river reach. It comes with no graphical user interface but it's a one-click tool. Just provide your input and let HABFUZZ provide you the output.
