Statistical Method

  • Regression Discontinuity and Interrupted Time Series analysis has long confused me. I found a presentation of University of Washington that discusses the differences. It is almost the only place that I found this information.  It seems like the biggest difference is that ITS relies on population data and RD on individual data. Overall RD is more robust than ITS.


  • Conditional equations in Latex. Answers from here.
  • \[
        \frac{x^2-x}{x},& \text{if } x\geq 1\\
        0,              & \text{otherwise}

    However, This code generate equation without numbering. To change it, we remove \[ and \] and replace with \begin{equation} and \end{equation}. Another thing to modify is when we write functions this why, the format of \sum becomes its in-line format – the beginning and end of the range of independent variable appears to the right of the capital sigma. To change that, use \sum\limits_{i=1}^{m_y} instead of \sum_{i=1}^{m_y}.
