Adjust spline knots in spreadsheet
Adding new knot - expand piece wise spline function
If( x≤Element(X,2),Element(Splines,1),
Element(X,2)≤x≤Element(X,3),Element(Splines,2),
Element(X,3)≤x≤Element(X,4),Element(Splines,3),
Element(X,4)≤x≤Element(X,5),Element(Splines,4),
x≥Element(X,5),Element(Splines,5))
