A companion function to `gpdpgrow`

1 2 3 | ```
## S3 method for class 'gpdpgrow'
predict_functions(object, J = 500, test_times,
time_points = NULL, sn_order = NULL, ...)
``` |

`object` |
Object of class |

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

`test_times` |
A numeric vector holding test times at which to predict GP function values
Will use the estimated covariance parameters from the training data to predict
functions at the test_times for the |

`time_points` |
Inputs a vector of common time points at which the collections of functions were
observed (with the possibility of intermittent missingness). The length of |

`sn_order` |
An integer vector of length, |

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

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

Intended as a companion function for `gpdpgrow`
