GetCovariance {Delta} | R Documentation |

This function calculate covariance for combinations Cov(Delta,Delta), Cov(Delta,Pi) and Cov(Pi,Pi).

```
GetCovariance(mx, Delta, Pi, B)
```

`mx` |
Matrix. Modified matrix to have a solution. Usually GetMx$M1 for k>2 and GetMx$M2 in case of k = 2. |

`Delta` |
Vector. Each element indicate the probability of recognize an element i. |

`Pi` |
Vector. Each element indicate the probability of classify at random an element in category i. |

`B` |
Double. Numerical solution to the equation given by the model. |
