=== PC4. Summarize aggregate relationships between outcome and predictor variables === The outcome variable we care about here is a dichotomous indicator for whether each traffic stop resulted in a police search (of either the driver or the vehicle) being conducted. Summarize the relationship between each of the predictor variables (<code>date</code>, <code>vehicle_year</code>, <code>subject_race</code>, and <code>subject_sex</code>) and the outcome variable (<code>search_conducted</code>). For continuous predictors, be sure to include visual summaries. For categorical predictors, focus on providing cross-tabulations that report conditional summary statistics within groups (for example, compare the numbers of searches conducted across the two categories of <code>subject_sex</code>).
