Ordered decomposition of gross gain — decompGg

Decomposes gross gain into interest, mortality, and expense components in a user-specified order.

Usage

decompGg_disc(
  VtG,
  Vt1G,
  G,
  i_assumed,
  q_assumed,
  r_assumed = 0,
  e_assumed = 0,
  s_assumed = 0,
  i_actual,
  q_actual,
  r_actual = 0,
  e_actual = 0,
  s_actual = 0,
  b = 1,
  order = c("interest", "mortality", "expense")
)

Arguments

VtG: Gross reserve at duration t.
Vt1G: Gross reserve at duration t + 1.
G: Gross premium.
i_assumed: Assumed annual effective interest rate.
q_assumed: Assumed mortality probability.
r_assumed: Assumed percent-of-premium expense rate.
e_assumed: Assumed per-policy expense.
s_assumed: Assumed settlement expense.
i_actual: Actual annual effective interest rate.
q_actual: Actual mortality probability.
r_actual: Actual percent-of-premium expense rate.
e_actual: Actual per-policy expense.
s_actual: Actual settlement expense.
b: Benefit amount.
order: Character vector containing "interest", "mortality", and "expense" exactly once.

Value

For scalar input, a named numeric vector. For vectorized input, a numeric matrix with columns total_gain, interest, mortality, expense, and check.

Details

For scalar input, the function returns a named numeric vector. For vectorized input, it returns a numeric matrix with one row per calculation.
