Fig. 2From: The kernel-weighted local polynomial regression (KwLPR) approach: an efficient, novel tool for development of QSAR/QSAAR toxicity extrapolation modelsSchematic representations of extrapolation at various polynomial’s orders are illustrated using simulated data. The polynomials order ranges from 1 (a) to 4 (d). The brown dashed lines represent the 95% confidence interval limitsBack to article page
