Extract association rules from an object created by the `createdatadiscrete`

function, using discrete time regression models to assess the significance of the extracted rules.

seqerulesdisc(fsubseq, datadiscr, tsef, pvalue=0.1, supvars=NULL,
adjust=TRUE, topt=FALSE, link="cloglog", dep=NULL)
``` |

`fsubseq` |
an object created using the |

`datadiscr` |
the object created by the |

`tsef` |
the data frame containing the original time-to-event dataset (equivalent to the |

`pvalue` |
the default threshold p-value to consider an association rule as significative, default is 0.1 |

`supvars` |
a vector of variable names to be used as control variables in the regression models (experimental) |

`adjust` |
if set to TRUE, a Bonferroni adjustment is applied to the p-value threshold specified in the |

`topt` |
if set to TRUE, use an alternative algorithm to extract the rules (very experimental) ; default to FALSE |

`link` |
the link function to be used in the generalized linear regression model. To obtain hazard ratios, use the complementary log-log link function ("cloglog", as default). The other choice is to use a logit link function ("logit"). |

`dep` |
if set to NULL, test all possible association rules. If an event is set, the function will only test association rules ending with this event |

This function uses a list of subsequences created by the `seqefsub`

function from the TraMineR package and tests each possible association rules. It then shows the association rules whose significance, assessed using a discrete time regression model, is higher than the specified p-value threshold.

The algorithm is described in the Müller et al. (2010) article, even though this function uses a discrete time regression model instead of the Cox regression model described in the article. A more complete explanation of the method is available in Müller (2011).

a list with one person-period data frame by event, where the dependent event is different each time. Please see the attached data file and code for an example.
