A system and a method for determining a percentage of recycled polyethylene terephthalate present in a test sample includes selecting a contaminant from a set of known contaminants. At least one predictor analyzes is identified from a group of predictor analyzes as being a statistically independent predictor analyzes of a presence of the selected contaminant. Predicting a percent recycled polyethylene terephthalate, identifying at least one set of best subsets of the statistically independent predictor analyzes of percent recycled polyethylene terephthalate and refining a percent recycled polyethylene terephthalate statistical model to a final predicted percent recycled polyethylene terephthalate model.
