Arguments

object

An object of class 'LinearLink'

ex_target

A value of life expectancy for which we want to derive the rotated vx

e0_u

Ultimate value of life expectancy. At this point the rotation process reaches its maximum efficiency. Here. e0_u = 80 is taken as the default.

e0_threshold

Level of life expectancy where the rotation should begin. If rotated_vx is computed for ex_target <= e0_threshold then no difference will be observed.

e0_conv

Set limit for convergence. For life expectancy a birth the default value is 130.

p_

The power to the smooth-weight function, p_, takes values between 0 and 1, which makes the rotation faster at starting times and slower at ending times. Here, p = .5 is taken as the default
