get_example_design {adestr} | R Documentation |

## Generate an exemplary adaptive design

### Description

The design was optimized to minimize the expected sample size under the alternative hypothesis for a one-armed trial. The boundaries are chosen to control the type I error at 0.025 for a normally distributed test statistic (i.e. known variance). For an alternative hypothesis of mu=0.4, the overall power is 80%.

### Usage

```
get_example_design(two_armed = FALSE, label = NULL)
```

### Arguments

`two_armed` |
(logical) determins whether the design is for one- or two-armed trials. |

`label` |
(optional) label to be assigned to the design. |

### Value

an exemplary design of class `TwoStageDesign`

. This object
contains information about the sample size recalculation rule `n2`

, the
futility and efficacy boundaries `c1f`

and `c1e`

and the
second-stage rejection boundary `c2`

.

### Examples

```
get_example_design()
```
