# CEL: Constrained equal losses rule In ClaimsProblems: Analysis of Conflicting Claims

 CEL R Documentation

## Constrained equal losses rule

### Description

This function returns the awards vector assigned by the constrained equal losses rule (CEL) to a claims problem.

### Usage

```CEL(E, d, name = FALSE)
```

### Arguments

 `E` The endowment. `d` The vector of claims. `name` A logical value.

### Details

Let E≥ 0 be the endowment to be divided and let d be the vector of claims with d≥ 0 and such that the sum of claims exceeds the endowment.

The constrained equal losses rule (CEL) equalizes losses under the constraint that no award is negative. Then, claimant i receives the maximum of zero and the claim minus a number λ ≥ 0 chosen so as to achieve balance.

CEL(E,d)=(max{0,di-λ}).

CEA and CEL are dual rules.

### Value

The awards vector selected by the CEL rule. If name = TRUE, the name of the function (CEL) as a character string.

### Examples

```E=10
d=c(2,4,7,8)
CEL(E,d)
# CEL and CEA are dual: CEL(E,d)=d-CEA(D-E,d)
D=sum(d)
d-CEA(D-E,d)
