lactcurves: Lactation Curve Parameter Estimation
AllCurves() runs multiple lactation curve models and extracts selection criteria for each model.
This package summarises the most common lactation curve models from the last century and provides a tool
for researchers to quickly decide on which model fits their data best to proceed with their analysis.
Start parameters were optimized based on a dataset with 1.7 million Holstein-Friesian cows. If convergence fails,
the start parameters need to be manually adjusted.
The models included in the package are taken from:

The selection criteria measure the goodness of fit of the model and include:
Residual standard error (RSE),
R-square (R2),
log likelihood,
Akaike information criterion (AIC),
Akaike information criterion corrected (AICC),
Bayesian Information Criterion (BIC),
Durbin Watson coefficient (DW).
The following model parameters are included:
Residual sum of squares (RSS),
Residual standard deviation (RSD),
F-value (F) based on F-ratio test.
