Functions to Automatically Generate Scorecards

```
auto_scorecard(
feature = accepts,
key_var = "application_id",
y_var = "bad_ind",
sample_rate = 0.7,
base0 = FALSE,
points0 = 600,
odds0 = 1/20,
pdo = 50,
k = 2,
max_depth = 3,
tree_p = 0.1,
missing_rate = 0,
single_var_rate = 1,
iv_set = 0.02,
char_to_number = TRUE,
na.omit = TRUE
)
```

`feature` |
A data.frame with independent variables and target variable. |

`key_var` |
A name of index variable name. |

`y_var` |
A name of target variable. |

`sample_rate` |
Training set sampling percentage. |

`base0` |
Whether the scorecard base score is 0. |

`points0` |
Base point. |

`odds0` |
odds. |

`pdo` |
Point-to Double Odds. |

`k` |
Each scale doubles the probability of default several times. |

`max_depth` |
Set the maximum depth of any node of the final tree, with the root node counted as depth 0. Values greater than 30 rpart will give nonsense results on 32-bit machines. |

`tree_p` |
Meet the following conversion formula: minbucket = round( p*nrow( df )).Smallest bucket(rpart):Minimum number of observations in any terminal <leaf> node. |

`missing_rate` |
Data missing rate, variables smaller than this setting will be deleted. |

`single_var_rate` |
The maximum proportion of a single variable, the variable greater than the setting will be deleted. |

`iv_set` |
IV value minimum threshold, variable IV value less than the setting will be deleted. |

`char_to_number` |
Whether to convert character variables to numeric. |

`na.omit` |
na.omit returns the object with incomplete cases removed. |

A list containing data, bins, scorecards and models.
