## Extract Population-Level Estimates

### Description

Extract the population-level ('fixed') effects
from a `brmsfit`

object.

### Usage

```
## S3 method for class 'brmsfit'
fixef(
object,
summary = TRUE,
robust = FALSE,
probs = c(0.025, 0.975),
pars = NULL,
...
)
```

### Arguments

`object` |
An object of class |

`summary` |
Should summary statistics be returned
instead of the raw values? Default is |

`robust` |
If |

`probs` |
The percentiles to be computed by the |

`pars` |
Optional names of coefficients to extract. By default, all coefficients are extracted. |

`...` |
Currently ignored. |

### Value

If `summary`

is `TRUE`

, a matrix returned
by `posterior_summary`

for the population-level effects.
If `summary`

is `FALSE`

, a matrix with one row per
posterior draw and one column per population-level effect.

### Examples

```
## Not run:
fit <- brm(time | cens(censored) ~ age + sex + disease,
data = kidney, family = "exponential")
fixef(fit)
# extract only some coefficients
fixef(fit, pars = c("age", "sex"))
## End(Not run)
```
