# From rates to probabilities

### Description

`cetotrans`

calculates transition probabilities from colonization and
extinction rates for a determined interval of time, when provided.

### Usage

1 |

### Arguments

`c` |
Colonization rate. |

`e` |
Extinction rate. |

`dt` |
Interval of time. |

### Details

Given a pair of colonization and extinction rates, we can calculate the transition probabilities with the following equations:

*T_{01} = (e
/ (c + e)) * (1 - exp( - (c + e) * dt))*

*T_{10} = (c / (c + e)) * (1 -
exp( - (c + e) * dt))*

### Value

The transition probabilities T_01 and T_10 of the Markov chain associated with the specified colonization and extinction rates.
