متن کاملClassification and regression tree (CART) analysis for indicator bacterial concentration prediction for a Californian coastal area.
The study used existing indicator bacterial data and a number of physicochemical parameters that can be measured instantaneously to determine if a decision tree approach, especially classification and regression tree, could be used to predict bacterial concentrations in timely manner for beach closure management. Each indicator bacteria showed different tree structures and each had its own sign...
