expgrowth-class: Class '"expgrowth"'

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

Class "expgrowth"

Description

The class "expgrowth" contains the results of the exponential_growth() function. Use summary(expgrowth) for results summary.

Objects from the Class

Objects can be created by the function exponential_growth.

Slots

exp_gr:

Object of class numeric Exponential growth rate

y_0:

Object of class numeric Baseline

R0:

Object of class numeric Basic reproduction number, derived from exponential growth model

doubling:

Object of class numeric Doubling rate, derived from exponential growth model

model_data:

Object of class lm OLS model

config:

Object of class list Model fit configurations

Methods

summary

signature(object = "expgrowth"): Prints a summary of expgrowth objects

print

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