Description Usage Arguments Value Examples

When extracting interaction patterns from a fitted XGBoost model to fit a linear regression model, not all interaction terms can be used. Transformed features that come from the same original feature can not be included in the same interaction term. For example, we can't have a two way interaction term 'basisFICO_8:basisFICO_2' or a three way interaciton term 'basisLTV_5:normTerm:basisLTV_3'.

1 | ```
input_filter(termName, matchName)
``` |

`termName` |
Character string indicating name of the interaction term. |

`matchName` |
Character string representing a pattern for matching, e.g., 'FICO'. |

An integer representing number of times 'matchName' appears in 'termName'

1 | ```
input_filter(termName = 'basisFICO_8:basisFICO_2', matchName = 'FICO')
``` |
