## Linear correlation

### Description

Linear correlation for Roy's bivariate geometric model

### Usage

```
corbivgeomRoy(theta1, theta2, theta3)
```

### Arguments

`theta1` |
paramater |

`theta2` |
paramater |

`theta3` |
paramater |

### Value

the value of Pearson's linear correlation - see Barbiero (2018). The linear correlation for Roy's bivariate geometric distribution is negative (or null, for `\theta_3=1`

) for any feasible choice of its parameters
