"sbm_ci"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 can be created by the function confint(sbm).
R_0A:Object of class "numeric" Model result: spatial reproduction number \(R_{0A}\)
integrals:Object of class "numeric" Model result: integrals \(S_A\), \(I_A\), and \(R_A\)
velocity:Object of class "numeric" Model result: velocity measures \(t_{FE}\) and \(t_{LE}\)
occ_regions:Object of class "data.frame" Model result: Occurence at regional level
cases_by_date:Object of class "data.frame" Total cases by date
cases_by_region:Object of class "data.frame" Cumulative cases by region
input_data:Object of class "data.frame" Input data
data_statistics:Object of class "numeric" Diagnostics of input data
col_names:Object of class "character" Column names in input data
integrals_ci:Object of class "list" Confidence intervals for integrals \(S_A\), \(I_A\), and \(R_A\)
velocity_ci:Object of class "list" Confidence intervals for velocity measures \(t_{FE}\) and \(t_{LE}\)
R_0A_ci:Object of class "numeric" Confidence intervals for spatial reproduction number \(R_{0A}\)
iterations:Object of class "data.frame" Results of bootstrap sampling iterations
ci:Object of class "numeric" Lower and upper confidence intervals based on user input
config:Object of class "list" Configuration details for bootstrap sampling
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 \(R_{0A}\)
signature(x = "sbm_ci"): Prints an sbm_ci object; use summary(sbm_ci) for results
signature(object = "sbm_ci"): Prints an sbm_ci object; use summary(sbm_ci) for results
signature(object = "sbm_ci"): Prints a summary of sbm_ci objects (bootstrap confidence intervals for Swash-Backwash Model estimates)
