Carry out a functional analysis of variance (ANOVA) of a `GaSPModel`

object
and generate plotting coordinates for its estimated main and 2-input joint effects.

1 | ```
Visualize(GaSP_model, x_description, main_percent = 0, interaction_percent = 0)
``` |

`GaSP_model` |
Object of class |

`x_description` |
A data frame describing the input variables.
See |

`main_percent` |
An optional minimum percentage of variation explained by an input's main effect to return the effect's plotting coordinates; the default of zero gives plotting coordinates for all inputs. |

`interaction_percent` |
An optional minimum percentage of variation explained by the interaction effect of a pair of inputs to return the plotting coordinates for their joint effect (main effects plus interaction effect); the default of zero gives plotting coordinates for all pairs of inputs. |

If there are many inputs, to avoid excessive plotting of
many trivial joint effects set `interaction_percent = 1`

say.

A list with the following elements:

`anova_percent` |
A data frame containing the ANOVA percentages for all main effects and 2-input interaction effects. |

`main_effect` |
A data frame with plotting coordinates for the estimated main effects. |

`joint_effect` |
A data frame with plotting coordinates for the estimated 2-input joint effects. |

`total_percent` |
Total percentage of the prediction variation accounted for by all main effects and 2-input interaction effects. |

`average` |
Overall average of the prediction function, averaged with respect to all inputs. |

`SE_average` |
Standard error of the overall average. |
