Warning in tidy.brmsfit(x, ..., effects = "fixed"): some parameter names
contain underscores: term naming may be unreliable!
✖ Unable to identify the list of variables.
This is usually due to an error calling `stats::model.frame(x)`or `stats::model.matrix(x)`.
It could be the case if that type of model does not implement these methods.
Rarely, this error may occur if the model object was created within
a functional programming framework (e.g. using `lappy()`, `purrr::map()`, etc.).

Using the data from the National Election Studies survey of US citizens, we will be exploring whether there is a relationship between sex and voting behavior. Our analysis might encounter variability due to discrepancies in self-reported voting behavior, where respondents may claim to have voted for one candidate but actually voted for another. Preliminary results indicate that males are more likely to vote for a specific candidate. A key quantity of interest (QoI) in our study is the proportion of males who voted for this candidate, estimated at 60% with a 95% confidence interval ranging from 55% to 65%. This measure of uncertainty reflects the potential variability in our estimate due to sampling and reporting errors.
