Perform a Bayesian estimation of the Exploratory reduced Reparameterized Unified

Model ('ErRUM') described by Culpepper and Chen (2018).

### Installation

You can install `errum` from CRAN using:

```{r cran-installation, eval = FALSE}

install.packages("errum")

```

Or, you can be on the cutting-edge development version on GitHub using:

```{r gh-installation, eval = FALSE}

if(!requireNamespace("remotes")) install.packages("remotes")

remotes::install_github("tmsalab/errum")

```

### Usage

To use the `errum` package, load it into _R_ using:

```{r example, message = FALSE}

library("errum")

```

From there, the errum model can be estimated using:

```{r errum-est, eval = FALSE}

errum_model = errum(, , chain_length = 10000)

```

### Authors

James Joseph Balamuta, Steven Andrew Culpepper, and Jeffrey A. Douglas
