# To compare sub-regression structures

### Description

Compares two sub-regression structures, considering one of them as the "true one".

### Usage

1 | ```
compare_struct(trueZ = trueZ, Zalgo = Zalgo, all = TRUE, mode = "NULL")
``` |

### Arguments

`trueZ` |
first structure (binary adjacency matrix) |

`Zalgo` |
second structure (binary adjacency matrix) |

`all` |
(boolean) Also compute the ratio for each stat. |

`mode` |
how to modify the structures before comparison. mode=c("NULL","hybrid","clique","sym") It allows to compare groups instead of exact sub-regressions. Does nothing by default. |

### Value

`true1` |
Number of links that exist in both matrices |

`false1` |
Number of links that exist only in Zalgo |

`false0` |
Number of links that exist only in trueZ |

`deltadr` |
Number of sub-regressions in trueZ - Number of sub-regressions in Zalgo (i.e. : negative if too much sub-regressions in Zalgo) |

`true_left` |
Number of variables redundant in both matrices |

`false_left` |
Number of variables redundant in Zalgo but not in trueZ |

`ratio_true1` |
ratio of links in trueZ that exist also in Zalgo |

`ratio_true0` |
ratio of links not in trueZ that don't exist in Zalgo. |
