 <p>We can think of the specification curve analysis as a factorial design in which we investigate the influence of different types of analytical choices on a resulting coefficient or test statistic. One way to investigate these effects is to ask how much variance in the specification curve is explained by what (or which combination of) analytical choices.</p>
 <p>In a first step, we therefore have to estimate a simple multilevel model without predictors, yet with specific random effects that represent the analytical choices.</p>

 <p>You might ask yourself why we did not include the multilevel model estimation in the <code><a href="../reference/icc_specs.html">icc_specs()</a></code> function. The reason is straight-forward: In many cases, it might be of interest to decompose the variance in different ways (e.g., including interactions between the analytical choices). In this case, we only need to specify the respective multilevel model (with alternative random effects) and we can again obtain a result table of a plot.</p>

 We can think of the specification curve analysis as a factorial design in which we investigate the influence of different types of analytical choices on a resulting coefficient or test statistic.
 One way to investigate these effects is to ask how much variance in the specification curve is explained by what (or which combination of) analytical choices.

 Second, we can alternatively use the function `plot_variance()` to obtain a visualization. The function calls `icc_specs()` automatically. We can hence pass the multilevel results object directly. Further customizations via the ggplot2-syntax is possible.

 You might ask yourself why we did not include the multilevel model estimation in the `icc_specs()` function. The reason is straight-forward: In many cases, it might be of interest to decompose the variance in different ways (e.g., including interactions between the analytical choices). In this case, we only need to specify the respective multilevel model (with alternative random effects) and we can again obtain a result table of a plot.
