## Point estimates for parameters from an angmcmc object

### Description

Point estimates for parameters from an angmcmc object

### Usage

```
pointest(object, fn = mean, par.name, comp.label, chain.no, ...)
```

### Arguments

`object` |
angular MCMC object. |

`fn` |
function, or a single character string specifying its name, to evaluate on MCMC samples to estimate
parameters. Defaults to |

`par.name` |
vector of names of parameters for which point estimates are to be computed. If |

`comp.label` |
vector of component labels (positive integers, e.g., |

`chain.no` |
vector of chain numbers whose samples are to be be used. in the estimation. By default all chains are used. |

`...` |
additional arguments to be passed to the function. |

### Value

Returns a matrix of point estimates, or vector of point estimates if `length(par.name)==1`

or `length(comp.label)==1`

.

### Examples

```
# first fit a vmsin mixture model
# illustration only - more iterations needed for convergence
fit.vmsin.20 <- fit_vmsinmix(tim8, ncomp = 3, n.iter = 20,
n.chains = 1)
# estimate parameters by sample mean
(est_mean <- pointest(fit.vmsin.20))
# estimate parameters by sample median
(est_median <- pointest(fit.vmsin.20, fn = median))
# estimate parameters by MAP
(est_median <- pointest(fit.vmsin.20, fn = "MODE"))
```
