The package provides a simple interface to fit a selection of these models, with arbitrary prior parameters, using MCMC and optimisation provided by [Stan](https://mc-stan.org/). A selection of functions are also provided to plot parts of these models and extract key parameters. \n\n## Example usage:\n\n```{r fit-demo, message = FALSE, warning = FALSE, results = \"hide\"}\nlibrary(rater)\n\nfit \u003c- rater(anesthesia, \"dawid_skene\") # Sampling output suppressed.\n```\n\nGet the posterior mean of the \"pi\" parameter.\n\n```{r extract-demo}\npoint_estimate(fit, \"pi\")\n```\n\nPlot the accuracy matrices of the raters.\n\n```{r plot-demo}\nplot(fit, \"raters\")\n```\n\n## Installation\n\n**rater** requires the **rstan** package to fit models. Detailed instructions to install **rstan** can be found [here](https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started)\n\n### CRAN \n\nInstall **rater** from CRAN with: \n\n```{r cran-installation, eval = FALSE}\ninstall.packages(\"rater\")\n```\n\n### Development\n\nTo install the development version of **rater** from GitHub run:\n\n```{r dev-installation, eval = FALSE}\n# install.packages(\"remotes\")\nremotes::install_github(\"jeffreypullin/rater\")\n```\n\n#### Installation notes:\n\n- When installing from source, i.e. when installing the development version or installing from CRAN on Linux, the **Stan** models in the package will be compiled - this will lead to an install time of few minutes. Please be patient - this compilation means that **no** compilation is required when using the package\n\n- During compilation many warnings may be displayed in the terminal; these are harmless but impossible to suppress.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjeffreypullin%2Frater","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjeffreypullin%2Frater","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjeffreypullin%2Frater/lists"}
