fit_growth_rate: Fit a growth rate model to time series cases.

Description

This function fits a growth rate model to time series cases and provides parameter estimates along with confidence intervals.

Usage

fit_growth_rate(
  cases,
  population = NULL,
  level = 0.95,
  family = c("quasipoisson", "poisson")
)

Value

A list containing:

• 'fit': The fitted growth rate model.

• 'estimate': A numeric vector with parameter estimates, including the growth rate and its confidence interval.

• 'level': The confidence level used for estimating parameter confidence intervals.

Arguments

cases

An integer vector containing the time series cases.

population

An integer vector containing the time series background population.

level

The confidence level for parameter estimates, a numeric value between 0 and 1.

family

A character string specifying the family for modeling. Choose between 'poisson', or 'quasipoisson'. Must be one of: character, family-generator, or family object.

Examples

# Fit a growth rate model to a time series of counts
# (e.g., population growth)
data <- c(100, 120, 150, 180, 220, 270)
fit_growth_rate(
  cases = data,
  level = 0.95,
  family = "poisson"
)
