The L-Curve Criterion as a Model Selection Tool in PLS Regression

Algorithm 1

The algorithm as presented by Hansen et al. [6].

(1)	Initialize
(2)	Stage one: while
(3)
(4)	Create a pruned L-curve consisting of the largest line segments.
(5)	For each corner location routine
(6)	Locate the corner using the pruned L-curve.
(7)	Add the corner to the list:
(8)
(9)	Stage two: if then ; return.
(10)	Otherwise for
(11)	Compute the slope associated with point in L.
(12)	If then ; return.
(13)	Otherwise let .
