A companion function to `gmrfdpgrow`

1 2 | ```
## S3 method for class 'gmrfdpgrow'
predict_functions(object, J = 500, T_test, ...)
``` |

`object` |
Object of class |

`J` |
Scalar denoting number of draws to take from posterior predictive for each unit.
Defaults to |

`T_test` |
The number of equally-spaced time points to predict the iGMRF functions ahead of
of the functions estimated at |

`...` |
further arguments passed to or from other methods. |

out A list object containing containing two matrices; the first is a P x (N*T) matrix of predicted function values for each of P sampled iterations. N is slow index and denotes the number of experimental units. The second matrix is an N x T average over the P sampled draws, composed in Rao-Blackwellized fashion.

Intended as a companion function for `gmrfdpgrow`
