Nosocomial transmission data simulation with fixed dated of admission and discharge. Swab test results and genetic information are generated.

`day_adm` |
Vector of admission dates (integer values). |

`day_dis` |
Vector of discharge dates (integer values). Must be same length as |

`p` |
Probability of carriage on admission. |

`z` |
Swab test sensitivity. |

`b` |
Transmission rate. |

`gamma` |
Within host/group genetic diversity (geometric distribution parameter). |

`gamma_gl` |
Between host/group genetic diversity (geometric distribution parameter). |

`genpar` |
Group clustering parameter (model 1), or transmission chain parameter (model 2). See details below. |

`testdays` |
Number of days between each carriage test/isolate collection. |

`model` |
Genetic diversity model (1: Importation clustering model, 2: Transmission chain model). See details below. |

We implement two different models of genetic diversification. Model 1 is the importation clustering model, in which each infected host belongs to a group. The probability that a new importation belongs to a new group is `genpar`

. All hosts within the same transmission chain belong to the same group. Pairwise genetic distances are sampled from geometric distributions with parameters `gamma`

and `gamma_gl`

for within-group and between-group pairs respectively. Model 2 is the transmission chain model, in which genetic distances increase as hosts are further separated in the transmission tree. Genetic distances between hosts separated by `k`

transmission links are drawn independently from the geometric distribution with parameter `gamma`

x `genpar`

^`k`

. Genetic distances between hosts in independent transmission chains are drawn from a geometric distribution with parameter `gamma_gl`

.

Returns a list of simulated data;

`epi` |
Matrix of epidemiological data, consisting of columns patient ID, day of admission, day of discharge, time of colonization, source of infection, and infection group. |

`resmat` |
Matrix of test results. Each row represents the corresponding patient in |

`distmat` |
Pairwise genetic distance data. Each row and column corresponds to patient ID in |

`patientseqIDs` |
Vector of patient IDs corresponding to the rows and columns of |

`simulate_data`

to additionally generate admission and discharge dates.
