dcm.design.effcy {choiceDes} | R Documentation |

## INTERNAL: Calculate design efficiencies

### Description

Internal function to calculate mathematical efficiencies of designs.

### Usage

```
dcm.design.effcy(des)
```

### Arguments

`des` |
An effects-coded design to be evaluated. |

### Details

Calculates overall `D`

-efficiency, the variance-covariance matrix,
and standard deviations for each parameter from an effects coded design.

Called internally by `dcm.design`

and `dcm.design.cand`

.

### Value

`D` |
Overall |

`V` |
Variance-covariance matrix derived from |

`s` |
Parameter standard deviations: |

, `dcm.design.cand`

### Examples

```
des <- dcm.design(c(3,3,4,3), 10, 8, 3)$effects$design
eff <- dcm.design.effcy(des)
```
