# Simulate data to mimic the GPS observations and the DR path.

### Description

Simulate data from our Bayesian melding model with Brownian Bridge and Brownian Motion (See the model description in `BMAnimalTrack`

).

### Usage

1 2 |

### Arguments

`T` |
Number of time points in the animal's path and DR path. |

`K` |
Number of GPS observations. |

`s2H` |
Variance parameter for Brownian Bridge. |

`s2D` |
Variance parameter for the Brownian motion. |

`s2G` |
Variance of the measurement error in the GPS observations. |

`gind` |
Optional. The time points where the GPS observations are obtained. Default is randomly generating from 1:T. |

`betaVec` |
Coefficients in the function |

`dMx` |
Design matrix of dimension T. Default the polynomials. |

`A` |
Start point of the path. Default 0. |

`B` |
End point of the path. Default 0. |

`scale` |
Logical (TRUE of FALSE). Whether to standardize the columns of |

### Value

A data list with the following elements:

`eta` |
The simulated path of the animal, |

`Y` |
The GPS observations, |

`Ytime` |
The time points where the GPS observations are available, |

`X` |
Dead-Reckoned path |
