PIN | R Documentation |
This function returns the awards vector assigned by the Piniles' rule (PIN) to a claims problem.
PIN(E, d, name = FALSE)
E |
The endowment. |
d |
The vector of claims. |
name |
A logical value. |
Let E≥ 0 be the endowment to be divided and d the vector of claims with d≥ 0 and such that D=∑ di ≥ E, the sum of claims D exceeds the endowment.
The Piniles' rule coincides with the constrained equal awards rule (CEA) applied to the problem (E, d/2) if the endowment is less or equal than the half-sum of the claims, D/2. Otherwise it assigns to each claimant i half of the claim, di/2 and, then, it distributes the remainder with the CEA rule. Therefore:
If E≤ D/2 then,
PIN(E,d)=CEA(E,d/2).
If E≥ D/2 then,
PIN(E,d)=d/2+CEA(E-D/2,d/2).
The awards vector selected by the PIN rule. If name = TRUE, the name of the function (PIN) as a character string.
