sa.GT: Sensitivity analysis of reproduction ratio with varying GT distribution

Description

Sensitivity analysis of reproduction ratio with varying GT distribution.

Usage

sa.GT(incid, GT.type, GT.mean.range, GT.sd.range, begin = NULL, end = NULL, est.method, t = NULL, date.first.obs = NULL, time.step = 1, ...)

Arguments

incid
incident cases
GT.type
Type of distribution for GT (see GT.R for details)
GT.mean.range
mean used for all GT distributions throughout the simulation
GT.sd.range
Range of standard deviation used for GT distributions. Must be provided as a vector.
begin
begin date of the estimation of epidemic
end
end date of estimation of the epidemic
est.method
Estimation method used for sensitivity analysis. Requires a method computing a proper R0 value (and not an instantaneous R(t))
t
Dates vector to be passed to estimation function
date.first.obs
Optional date of first observation, if t not specified
time.step
Optional. If date of first observation is specified, number of day between each incidence observation
...
parameters passed to inner functions

Value

$GT.type
Distribution law for GT.
$GT.mean
Range of means used for tested GTs.
$GT.sd
Range of standard deviations used for tested GTs.
$R
Computed value for Reproduction Number given GT.type, GT.mean and GT.sd.
$conf.int[1]
The lower limit of 95% CI for R.
$conf.int[2]
The upper limit of 95% CI for R.

Details

By using different Generation Time (GT) distribution, different estimates of reproduction ratio can be analyzed.
