Description Usage Arguments Value Author(s) References Examples

This function provides real-time predictions of the final size and the turning point at the end of the epidemic for each built-in model and model averaged, as well as the incidence and the cumulative number of cases in future observations. Also this function, when all the built-in models are used, gives the AIC of each model, the model averaged weights and predicted incidence and cumulative cases.

## Object of the S3 class dengue
allmodelpredict(inc,time,pred,start=NULL,model)
``` |

`inc,time` |
Vector of equal length specifying incidence (number of reported cases per time unit) and time interval (from the start of outbreak). |

`pred` |
Number of observation in which the incidence and the cumulative number of cases will be predicted. |

`start` |
A list with the starting values of the model to be used for fitting the data. If model="all" the imput must be a list of a list with the starting values of Richards, 3P logistic, Sigmoid Emax, Gompertz, Weibull and 5P logistic model parameters. By default, the initial values are provided by self-starting functions (see argument start in |

`model` |
The nonlinear model to be used for fitting the data. Built-in models are "Richards"", "Logistic3P", "SigmEmax", "Gompertz", "Weibull" and "Logistic5P" (see argument model in |

An object with the parameter estimate for each built-in model and model averaged estimate for final size and turning point of outbreak. It is a list:

`Incidence ` |
All the available incidences |

`Time` |
All the available time points |

`PredTime` |
Period of time for which the prediction is required |

`AIC` |
The AIC for each built-in model and model averaged |

`tTable` |
A table with parameter estimates and t test. It is not available when all the model are used. |

`Weights` |
Model averaged weights. It is not availabe when is used only one built-in model |

`FinalSize` |
95% confidence interval and point estimate of the final size of outbreak for each built-in model and model averaged estimate |

`TurningPoint` |
95% confidence interval and point estimate of the turning point of outbreak for each built-in model and model averaged estimate |

`Predict` |
Predicted cumulative cases for each built-in model |

`PredictMA` |
Predicted cumulative cases for model averaged |

`PredInc` |
Predicted incidence for each built-in model |

`PredMAInc` |
Predicted incidence for model averaged |

`function.type` |
Name of the function |

`model.type` |
models used to estimate |

Generic functions such as plot and summary have methods to show the results of the fit
