Statistical Properties of News Coverage Data Lim, Eunju; Hahn, Kyu S.; Lim, Johan; Kim, Myungsuk; Park, Jeongyeon; Yoon, Jihee;
In the current analysis, we examine news coverage data widely used in media studies. News coverage data is usually time series data to capture the volume or the tone of the news media`s coverage of a topic. We first describe the distributional properties of autoregressive conditionally heteroscadestic(ARCH) effects and compare two major American newspaper`s coverage of U.S.-North Korea relations. Subsequently, we propose a change point detection model and apply it to the detection of major change points in the tone of American newspaper coverage of U.S.-North Korea relations.
