LineCon {ThreeWay}

Middle point location

Description

Checks whether the middle point is located below or on the line connecting its neighbors.

Usage

 LineCon(f1, f2, f3, fp1, fp2, fp3)

Arguments

f1

Goodness-of-fit value for the first point

f2

Goodness-of-fit value for the second point

f3

Goodness-of-fit value for the third point

fp1

Number of effective parameters for the first point

fp2

Number of effective parameters for the second point

fp3

Number of effective parameters for the third point

Value

ret

Value that indicates if the middle point is located below or on the line connecting its neighbors (0 if the middle point is not located below the line connecting its neighbors, 1 if the middle point is not located on the line connecting its neighbors)
