DengueRT (version 1.0.1)

changetimeFSTP: Changes over time of the final size and turning point estimates for each built-in model and model averaged.

Description

This function provides the changes over time of the final size and turning point estimates (for specific models and model average) from the time point required until the last time point available. The output of the function are two tables, one for final size and the other for turning point. the rows represent the data used for the estimation of the model parameters.

Usage

## Object of the S3 class dengue
changetimeFSTP(inc, time, ini, start = NULL)

Arguments

inc,time

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

ini

Time point from which is required to see the changes over time of the final size and turning point estimates

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.

Value

An object with the changes over time of the final size and turning point estimates for specific models and model average. It is a list:

Incidence

All the available incidences

Time

All the available time points

Period

Time period required to see the changes over time of the final size and turning point estimates

FSchangetime

A Table with the changes over time of the final size for the time period required

TPchangetime

A Table with the changes over time of the turning point for the time period required

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.
