compare_secondary_fits {biogrowth} | R Documentation |

## Model comparison and selection for secondary growth models

### Description

This function is a constructor for SecondaryComparison
a class that provides several functions for model comparison and model selection
for growth models fitted using `fit_secondary_growth()`

. Please see the help pages for
SecondaryComparison for further details.

Although it is not necessary, we recommend passing the models as a named list, as these names will later be kept in plots and tables.

### Usage

```
compare_secondary_fits(models)
```

### Arguments

`models` |
a (we recommend named) list of models fitted using |

### Examples

```
## We first need to fit some models
data("example_cardinal")
sec_model_names <- c(temperature = "Zwietering", pH = "CPM")
known_pars <- list(mu_opt = 1.2, temperature_n = 1,
pH_n = 2, pH_xmax = 6.8, pH_xmin = 5.2)
my_start <- list(temperature_xmin = 5, temperature_xopt = 35,
pH_xopt = 6.5)
fit1 <- fit_secondary_growth(example_cardinal, my_start, known_pars, sec_model_names)
known_pars <- list(mu_opt = 1.2, temperature_n = 2,
pH_n = 2, pH_xmax = 6.8, pH_xmin = 5.2)
fit2 <- fit_secondary_growth(example_cardinal, my_start, known_pars, sec_model_names)
## We can now pass the models to the constructor
comparison <- compare_secondary_fits(list(`n=1` = fit1,
`n=2` = fit2))
## The function includes several S3 methods for model selection and comparison
print(comparison)
plot(comparison)
plot(comparison, type = 2)
## The numerical indexes can be accessed using coef and summary
coef(comparison)
summary(comparison)
```
