Autocorrelation descriptors encoding lipophilicity, molar refractivity, the H-bonding acceptor and donor ability of the molecules and also indicator variables were used to describe 30 organic chemicals characterized by their adult and developmental toxicities to Hydra attenuata. A PLS regression analysis was successfully employed to derive a QSAR model allowing the simulation of both endpoints. Comparisons were made with orthogonal regression analysis and different nonlinear regression analyses.
