這個要感謝 ptt.cc 的前經濟板板主 publius 的分享. 如果學過計量經濟學, 應該會清楚的知道這篇的賣點. XD! A student was sitting in an econometric class taught by Prof White. The lecture was too difficult that few students understood it. "What is the lecture all about?" A student asked his friend who was sitting right next to him. "I don't quite understand it either. All I get is, it's just some noise...specifically, white noise. He said we can expect it to be nothing on average."
