Summary of LE0 Fits

Description

Summarizes parameter estimates and goodness-of-fit statistics for a fitted LE0 model.

Usage

## S3 method for class 'le0_fit'
summary(object, ...)

Arguments

object	A le0_fit object.
...	Additional arguments passed to methods.

Details

The summary typically includes:

• Asymptotic gas production (A)

• Fractional rate constant (k)

• Shape parameter (d)

• Residual Sum of Squares (RSS)

• Root Mean Squared Error (RMSE)

• R-squared (R²)

• Akaike Information Criterion (AIC)

• Bayesian Information Criterion (BIC)

The LE0 (Logistic-Exponential) model combines exponential fermentation kinetics with a logistic component to provide additional flexibility in curve shape without requiring an explicit lag phase.

The shape parameter d controls the curvature of the fermentation profile and can improve fit performance for sigmoidal gas production data.

Value

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