Calibration, Validation, and Simulation of TKTD Models [R package cvasi version 1.5.0]

cvasi: Calibration, Validation, and Simulation of TKTD Models

Eases the use of ecotoxicological effect models. Can simulate common toxicokinetic-toxicodynamic (TK/TD) models such as General Unified Threshold models of Survival (GUTS) and Lemna. It can derive effects and effect profiles (EPx) from scenarios. It supports the use of 'tidyr' workflows employing the pipe symbol. Time-consuming tasks can be parallelized.
