Designing an Interrupted Time Series Analysis to Evaluate Regulatory Impact on Fintech Innovations

Instruction: Outline a detailed plan for conducting an interrupted time series analysis to assess the causal impact of new financial regulations on the rate of fintech innovations.

Context: This question assesses the candidate's capability to design a robust causal inference study using interrupted time series analysis, a method particularly useful in evaluating the effect of interventions that occur at a specific point in time. The candidate should address data requirements, potential confounders, and how to statistically determine the impact of the regulatory change.
