risk_calculate {abcrlda} | R Documentation |

## Risk Calculate

### Description

Estimates risk and error by applying a constructed classifier (an object of class abcrlda) to a given set of observations.

### Usage

```
risk_calculate(object, x_true, y_true)
```

### Arguments

`object` |
An object of class "abcrlda". |

`x_true` |
Matrix of values for x for which true class labels are known. |

`y_true` |
A numeric vector or factor of true class labels. Factor should have either two levels or be a vector with two distinct values.
If |

### Value

A list of parameters where

`actual_err0` |
Error rate for class 0. |

`actual_err1` |
Error rate for class 1. |

`actual_errTotal` |
Error rate overall. |

`actual_normrisk` |
Risk value normilized to be between 0 and 1. |

`actual_risk` |
Risk value without normilization. |
