Log-likelihood test for comparing terms in ASReml-R models

## Usage

```
logl.test(
model.obj,
rand.terms = NULL,
resid.terms = NULL,
decimals = 3,
numeric = FALSE,
quiet = FALSE
)
```

## Arguments

- model.obj
An ASReml-R model object

- rand.terms
Random terms from the model. Default is NULL.

- resid.terms
Residual terms from the model. Default is NULL.

- decimals
Controls rounding of decimal places in output. Default is 3 decimal places.

- numeric
Return p-values as numeric? Default is that they are characters, where very small values shown as less than a small number. See

`details`

for more.- quiet
Logical (default:

`FALSE`

). Hide warnings and messages?

## Details

Typically p-values cannot be 0, and are usually just below some threshold of accuracy in calculation of probability.

## Examples

```
if (FALSE) {
library(asreml)
dat <- asreml::oats
dat <- dat[order(dat$Row, dat$Column),]
#Fit ASReml Model
model.asr <- asreml(yield ~ Nitrogen + Variety + Nitrogen:Variety,
random = ~ Blocks + Blocks:Wplots,
residual = ~ ar1(Row):ar1(Column),
data = dat)
oats.logl <- logl.test(
model.obj = model.asr, rand.terms = c("Blocks", "Blocks:Wplots"),
resid.terms = c("ar1(Row)", "ar1(Column)")
)
oats.logl
}
```
