### Panel Model with Unit and Occasion Effects

Source: https://github.com/jepusto/clubsandwich/blob/main/paper_ClusterRobustTesting/ClusterRobustTesting_notes_and_variations.tex

This specification represents a common model for balanced panels, including additional fixed effects for each unique measurement occasion.

```latex
y_{jt} = \bm{r}_{jt} \bs\alpha + \gamma_j + \nu_t + \epsilon_{jt}
```

### Load MathJax for Mathematical Formulas

Source: https://github.com/jepusto/clubsandwich/blob/main/auxilliary/cluster-wild-bootstrap.html

This script dynamically loads the MathJax library to render mathematical formulas on the page. It is configured to use TeX-AMS-MML_HTMLorMML.

```javascript
(function () {
  var script = document.createElement("script");
  script.type = "text/javascript";
  script.src = "https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML";
  document.getElementsByTagName("head")[0].appendChild(script);
})();
```

### Difference-in-Differences Model

Source: https://github.com/jepusto/clubsandwich/blob/main/paper_ClusterRobustTesting/ClusterRobustTesting_FE_models.tex

Presents the analytic model used for the difference-in-differences design within the simulation study. This model accounts for cluster, unit, and time point effects.

```latex
y_hijk = _hk + _i + _j + _ijk,
```

### Apply Bootstrap Styling to Pandoc Tables

Source: https://github.com/jepusto/clubsandwich/blob/main/auxilliary/cluster-wild-bootstrap.html

This JavaScript function applies Bootstrap table classes to Pandoc-generated tables. It should be called when the document is ready.

```javascript
function bootstrapStylePandocTables() {
  $('tr.header').parent('thead').parent('table').addClass('table table-condensed');
}
$(document).ready(function () {
  bootstrapStylePandocTables();
});
```

### Data Generation Model

Source: https://github.com/jepusto/clubsandwich/blob/main/paper_ClusterRobustTesting/ClusterRobustTesting_FE_models.tex

Specifies the data-generating process for tri-variate outcome data, including unit means, treatment effects, and idiosyncratic errors. Used to simulate data for hypothesis testing performance evaluation.

```latex
y_hijk = _i + _hi + _ijk,
```

--------------------------------

### Basic Fixed Effects Panel Model

Source: https://github.com/jepusto/clubsandwich/blob/main/paper_ClusterRobustTesting/ClusterRobustTesting_notes_and_variations.tex

This equation describes a basic fixed effects panel data model where y_jt is the outcome, r_jt covariates, gamma_j a unit-specific intercept, and epsilon_jt the error term.

```latex
y_{jt} = \bm{r}_{jt} \bs\alpha + \gamma_j + \epsilon_{jt}
```
