R: Penalty function type Birgé-Massart 2

penalty_BirgeMassart_shape2 {PhylogeneticEM} | R Documentation

## Penalty function type Birgé-Massart 2

### Description

`penalty_BirgeMassart_shape2` is the penalty shape defined by : pen_shape = C*K_try + log(model_complexity). It dominates the penalty defined by `penalty_BirgeMassart_shape1`.

### Usage

    penalty_BirgeMassart_shape2(K, p, model_complexity, C = 2.5)

### Arguments

`K` | the number of shifts
`p` | the dimension of the data
`model_complexity` | the complexity of the set of models with dimension K.
`C` | a non-negative constant. Default is 2.5 (as suggested in Lebarbier 2005)

### Details

See Birgé Massart (2001). Must be applied to least-square criterion. This penalty should be calibrated using the slope heuristic.

### Value

value of the penalty.
