Summary of Dual Logistic Fits

Description

Summarizes parameter estimates and goodness-of-fit statistics for a fitted dual-pool logistic model.

Usage

## S3 method for class 'dual_logistic_fit'
summary(object, ...)

Arguments

object	A dual_logistic_fit object.
...	Additional arguments passed to methods.

Details

The summary typically includes:

• Rapid pool gas volume (V1F)

• Slow pool gas volume (V2F)

• Rapid pool rate constant (k1)

• Slow pool rate constant (k2)

• Lag time (lambda)

• Residual Sum of Squares (RSS)

• Root Mean Squared Error (RMSE)

• R-squared (R²)

• Akaike Information Criterion (AIC)

• Bayesian Information Criterion (BIC)

The Dual Logistic model partitions fermentation into rapidly and slowly degradable fractions, providing a biologically informative description of fermentation dynamics.

Value

A data frame containing parameter estimates and model diagnostics for each fitted bottle.
