## 5Criteria for the YES orNO prediction: If the Biowin3 (ultimate survey model) result is "weeks" or faster (i.e. "days",

**·~days** to weeks", or "weeks" AND the Biowin5 (MITI linearmodel) probability is >= 0.5, then the prediction is YES (readilybiodegradable)

. If this condition is not satisfied, the prediction is NO (not readilybiodegradable)

. This method is based on application of Bayesian analysis to readybiodegradationdata (see Help). Biowin5 and 6 alsopredict readybiodegradability, but for degradation in the OECD301C test only; using data from the Chemicals Evaluation andResearch Institute Japan (CERIJ) database.
