rotate_vx: Compute Rotated vx Coefficients

In mpascariu/MortalityEstimate: Indirect Estimation Methods for Measurement of Demographic Indicators

Description

This functions computes the rotation of the vx coefficients using the method presented in \insertCiteli2013;textualMortalityEstimate paper.

Usage

rotate_vx(
  object,
  ex_target,
  e0_u = 102,
  e0_threshold = 80,
  e0_conv = 130,
  p_ = 0.5
)

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
