# Summarize a continuous-time movement model

### Description

This function returns a list of biologically interesting parameters in human readable format, as derived from a continuous-time movement model.

### Usage

1 2 |

### Arguments

`object` |
A |

`level` |
Confidence level for parameter estimates. |

`level.UD` |
Confidence level for the Gaussian home-range area. |

`...` |
Unused options. |

### Value

If summary is called with a single `ctmm`

object output from `ctmm.fit`

, then a table is returned with low, maximum likelihood, and high estimates for the following possible parameters:

`tau`

The autocorrelation timescales.

`area`

The Gaussian home-range area, where the point estimate has a significance level of

`level.UD`

. I.e., the core home range is where the animal is located 50% of the time with`level.UD=0.50`

. This point estimate itself is subject to uncertainty, and is given confidence intervals derived from`level`

.`speed`

The Gaussian root-mean-square (RMS) velocity, which is a convenient measure of average speed.

If summary is called on a list of `ctmm`

objects output from `ctmm.select`

, then a table is returned with the model names and AIC differences, where "IID" denotes the uncorrelated bi-variate Gaussian model, "OU" denotes the continuous-position Ornstein-Uhlenbeck model, and "OUF" denotes the continuous-velocity Ornstein-Uhlenbeck-F model.

### Note

Confidence intervals on the autocorrelation timescales assume they are sufficiently greater than zero and less than infinity.
