sbm_ci-class: Class '"sbm_ci"'

In swash: Swash-Backwash Model for the Single Epidemic Wave

Class "sbm_ci"

Description

The class "sbm_ci" contains the results of the Swash-Backwash Model, confidence intervals for the model estimates, and the related input data as well as additional information. Use summary(sbm_ci) and plot(sbm_ci) for results summary and plotting, respectively.

Objects from the Class

Objects can be created by the function confint(sbm).

Methods

plot

signature(x = "sbm_ci"): Plots the results of bootstrap confidence intervals for the Swash-Backwash Model; one figure with six plots: S_A, I_A, R_A, t_{FE}, t_{LE}, and R_{0A}

print

signature(x = "sbm_ci"): Prints an sbm_ci object; use summary(sbm_ci) for results

show

signature(object = "sbm_ci"): Prints an sbm_ci object; use summary(sbm_ci) for results

summary

signature(object = "sbm_ci"): Prints a summary of sbm_ci objects (bootstrap confidence intervals for Swash-Backwash Model estimates)
