Assessing Risk of Fumonisin Contamination in Maize Using Near-Infrared Spectroscopy

Table 1

Two-way confusion matrix.

	Predicted by model
	Negative (fumonisin content <4000 μg/kg)	Positive (fumonisin content >4000 μg/kg)
Actual content
Negative (fumonisin content <4000 μg/kg)
Positive (fumonisin content >4000 μg/kg)

: number of correct negative predictions (maize samples with a mycotoxin content below the limit and properly classified); : number of incorrect positive predictions (maize samples with a mycotoxin content below the limit and improperly classified); : number of incorrect negative predictions (maize samples with a mycotoxin content above the limit and improperly classified), : number of correct positive predictions (maize samples with a mycotoxin content above the limit and properly classified).
