Partial Least Squares (PLS) Integrated Fourier Transform Infrared (FTIR) Approach for Prediction of Moisture in Transformer Oil and Lubricating Oil

Table 8

The average % RMSE of prediction using partial least squares regression (PLSR) and simple linear regression (SLR) based on 100 training/test sets (concentration ranges 0–5000 ppm).

Data	Prediction method	Lubricating oil (%)	Transformer oil (%)
Training	PLSR	14.15	24.16
	SLR	14.86	27.10
Test	PLSR	16.55	28.63
	SLR	16.53	30.95
