## Control values for order-constrained fit

### Description

The values supplied in the function call replace the defaults and a list with
all possible arguments is returned. The returned list is used as the control
argument to the `mc.est`

, `SO.LRT`

, and
`SO.trend.test`

functions.

### Usage

```
soControl(
method = c("ISDM", "EM"),
eps = 0.005,
max.iter = 5000,
max.directions = 0,
start = ifelse(method == "ISDM", "H0", "uniform"),
verbose = FALSE
)
```

### Arguments

`method` |
a string specifying the maximization method |

`eps` |
a numeric value giving the maximum absolute error in the log-likelihood |

`max.iter` |
an integer specifying the maximal number of iterations |

`max.directions` |
an integer giving the maximal number of directions considered at one step of the ISDM method. If zero or negative, it is set to the number of non-empty cells. A value of 1 corresponds to the VDM algorithm. |

`start` |
a string specifying the starting setup of the mixing distribution; "H0" puts weight only on constant vectors (corresponding to the null hypothesis of no change), "uniform" puts equal weight on all elements. Only a "uniform" start can be used for the "EM" algorithm. |

`verbose` |
a logical value; if TRUE details of the optimization are shown. |

### Value

a list with components for each of the possible arguments.
