{"product_id":"the-effect","title":"The Effect","description":"\u003cp\u003eThe Effect: An Introduction to Research Design and Causality is about research design  specifically concerning research that uses observational data to make a causal inference. It is separated into two halves  each with different approaches to that subject. The first half goes through the concepts of causality  with very little in the way of estimation. It introduces the concept of identification thoroughly and clearly and discusses it as a process of trying to isolate variation that has a causal interpretation. Subjects include heavy emphasis on data-generating processes and causal diagrams. Concepts are demonstrated with a heavy emphasis on graphical intuition and the question of what we do to data. When we add a control variable what does that actually do? Key Features:  Extensive code examples in R  Stata  and Python  Chapters on overlooked topics in econometrics classes: heterogeneous treatment effects  simulation and power analysis  new cutting-edge methods  and uncomfortable ignored assumptions  An easy-to-read conversational tone  Up-to-date coverage of methods with fast-moving literatures like difference-in-differences\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":44946056183861,"sku":"ByrdShop_1032125780","price":61.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9781032125787.jpg?v=1769921263","url":"https:\/\/atxbooks.com\/products\/the-effect","provider":"ATX Books","version":"1.0","type":"link"}
