Study of cyanotoxins presence from experimental cyanobacteria concentrations using a new data mining methodology based on multivariate adaptive regression splines in Trasona reservoir (Northern Spain)

► A MARS model is used as a predictive model of cyanotoxins presence. ► Cyanobacterial HABs are dangerous for people and the environment in fresh waters. ► The influence of the different variables in this process is studied in detail.
