Generational Changes in Support for Gun Laws: A Case Study in Computational Statistics

In the United States, support for gun control has been declining among all age groups since 1990; among young adults, support is substantially lower than among previous generations. Using data from the General Social Survey (GSS), I perform age-period-cohort analysis to measure generational effects. In this talk, I demonstrate a computational approach to statistics that replaces mathematical analysis with random simulation. Using Python and libraries like NumPy and StatsModels, we can define basic operations — like resampling, filling missing values, modeling, and prediction — and assemble them into a data analysis pipeline.
