Description Usage Arguments Value Examples

This method computes predicted outcome for each observation in the data frame using the tree model supplied as an input argument.

1 2 |

`i` |
the tree |

`data` |
A data frame containing the variables in the model. |

`main_model` |
A model in character format |

`partition_vars` |
A vector of partition variables |

`mtry` |
A Random subset of partition variables to be considered at each |

`new_test_data` |
A data frame representing test data for validating random forest model. This data is not used in in tree building process. |

`mobforest_controls` |
The mobforest_controls passed into mobforest.analysis |

`fraction` |
number of observations to draw without replacement (only relevant if replace = FALSE) |

`model` |
A model of class |

`family` |
A description of error distribution and link function to be used in the model. This parameter needs to be specified if generalized linear model is considered. The parameter "binomial()" is to be specified when logistic regression is considered and "poisson()" when Poisson regression is considered as the node model. The values allowed for this parameter are binomial() and poisson(). |

`prob_cutoff` |
In case of logistic regression as a node model, the predicted probabilities for OOB cases are converted into classes (yes/no, high/low, etc as specified) based on this probability cutoff. If logistic regression is not considered as node model, the prob_cutoff = NULL. By default it is 0.5 when parameter not specified (and logistic regression considered). |
